Icing Conference. This conference will provide you with a special 

opportunity to interact with professionals knowledgeable in all areas of 

safe aircraft operations. 

Advancements in technology over the past few years demand a 

continuing need for information sharing. This conference provides 

a unique forum for showcasing the progress that has been made 

in research, simulation, regulatory, safety and industry standards 

development related to aircraft and engine icing, deicing, detection 

and protection. 

Over eighty of the industry’s brightest professionals from around the 

world have contributed to the development of the technical program. 

This is a chance to share your views regarding aircraft deicing 

fluids, environmental considerations, simulation CFD, in-flight icing, 

rotorcraft icing, aircraft engine icing, icing physics, meteorology, and 

certification. It is our wish that you will enjoy both the scope and depth 

of these presentations. 

As you spend the week in the beautiful city of Seville, we are certain 

your time will be filled with stimulating conversation, the exchange 

of innovative ideas and the building of greater friendships with 

professionals from around the world. In addition, we hope you will find 

a few moments to enjoy the many one-of-a-kind attractions found 

only in Seville. 

Thank you for your continued support and participation in the 2007 

SAE Aircraft and Engine Icing Conference.

Things to Do and See in Seville 

Seville sits on the left bank of the 

Guadalquivir River and is located in 

Southwest Spain. It has approximately 

700,000 inhabitants, nearly half the 

population of the whole province. 

Its ancient history – which includes 

Roman and Islamic influence – has left 

its mark in the fascinating culture and 

architecture. In the 16th century, Seville 

(known as Sevilla in Spanish) became 

an important hub for travel and trade 

between Europe and the Americas. 

More recently, the city made headlines 

worldwide when it hosted the World 

Expo in 1992. 

Bullfighting, or corrida de toros, is 

something enjoyed or loathed by visitors 

and Spaniards alike. No matter your 

opinion, bullfighting is a tradition in 

Sevilla and the Plaza de Toros de la 

Maestranza is perhaps the best venue 

in all of Spain to watch the event. Even 

though the season is short, there are 

events taking place on September 29 

and 30. For more information, visit: 

www.exploreseville.com. 

Flamenco may have its birthplace in 

Seville, many argue this fact. The 

important thing to know is that the cradle 

of flamenco is in western Andalucia, and 

there are few better places to flamenco 

than Seville. Learn more by visiting: 

www.exploreseville.com. 

Parque Isla Magica amusement park 

is located on the original Expo92 site 

and is the only theme park in the world 

that is located right in the middle of 

the city. The amusement park, which 

opened in 1997, is centered around a

Park of Maria Luisa is one of the city’s 

largest parks with a surface area greater 

than 400,000 meters. It was originally 

built as a Romantic garden for the palace 

of San Telmo on the occasion of the 1929 

Latin American Exhibition. 

Palacio de Lebrija is located on calle Cuna 

and is perhaps the largest collection of 

roman mosaics in Seville, besides any 

public museum. Venturing upstairs there 

is much more to the palace than just the 

mosaics. 

Plaza Espana was constructed for the 

1929 World’s Fair under the plans of 

architect Anibal Gonzalez, the Plaza de 

Espana is located on the edge of the 

Parque Maria Luisa. 

Santa Cruz is the old Jewish quarter or 

juderia located next to the Cathedral and 

the Alcazar. With narrow streets and 

plenty of plazas it’s a great place to relax 

for a drink or a stroll in the evening. 

There is so much to see and do in Sevilla, 

please visit the below listed websites for 

additional information on shopping, cultural 

activities, museums, cathedrals, nightlife, 

day trips, restaurants, etc.

Immediately after takeoff the aircraft began a rapid roll, which continued despite 

the prompt application of full opposite aileron and rudder. The winglet contacted 

the runway shoulder, the outboard part of the wing detached and the aircraft 

struck the ground inverted, structurally separating the forward fuselage. Fuel 

released from ruptured tanks ignited and the wreckage slid to a halt on fire. The 

accident was not survivable. 

Numerous possible causes for the uncontrolled roll were identified but all except 

one were eliminated. It was concluded that the roll had resulted from the left 

wing stalling at an abnormally low angle of attack due to flow disturbance 

resulting from frost contamination of the wing. A relatively small degree of wing 

surface roughness had a major adverse effect on the wing stall characteristics 

and the stall protection system was ineffective in this situation. Seven safety 

recommendations were made.

Ms. Jeanne G. Mason 

Senior Specialist Engineer, Propulsion Systems Division 

Boeing Commercial Airplanes 

MONDAY 

Ms. Mason has the privilege of being a leader in the investigation 

of a new icing phenomenon – ice crystal accretion on warm 

engine surfaces. This pioneering work is particularly interesting 

because so little is known about the specific conditions that enable 

ice crystal build-up. Each new in-service event provides the 

opportunity for detective work; analysis of the weather conditions 

and the engine behavior provide clues to the nature of the ice accretion and shedding 

physics. Recognized as a specialist in engine icing at the Boeing Company, Ms. Mason 

has traveled world-wide to brief airline pilots about the nature of engine problems and 

the weather associated with them. 

A graduate of Case Western Reserve University with a Bachelor’s in Mechanical 

Engineering in 1986, Ms Mason joined Boeing Commercial Airplanes that same year. She 

received a Master’s of Science in Aeronautical Engineering from University of Washington 

in 1990. After working in Propulsion Structures and Propulsion Computational Fluid 

Dynamics, she found her niche in the Engine Operability group in 1994, and has enjoyed 

the challenges of that position ever since. In addition to the ever-present in-service 

engine icing issues, this role has involved certification and flight testing of new engine 

designs. 

Ms. Mason currently serves as the co-chair of two industry icing committees: the Engine 

Harmonization Working Group on Supercooled Large Drops and Mixed Phase Icing, and 

the SAE G-12 Engine Ground Icing Working Group. 

“The Ice Crystal Weather Threat to Engines” 

This presentation is an introduction to the recently recognized ice crystal threat to engines. While 

this problem has existed for many years, engine power loss events which were associated with flight 

near convective weather were not understood. They were initially thought to be related to heavy rain 

or hail instead of icing. This presentation will describe the data which initially misled investigators, 

and how the connection to icing was finally made. 

Avoiding commercial airline flight in these conditions is not practical, as it is difficult for flight crews 

to identify these weather conditions. A better solution to this problem is to make the engine robust 

to ice crystal accretion. 

The icing problem, unique to engines, involves ice crystals accreting on warm engine surfaces, 

followed by the ice shedding and causing power loss and damage. The industry faces many 

challenges to understand and address the problem of engine power loss due to ice crystals. 

Investigations are underway to understand the nature of the atmospheric conditions, and to simulate 

the ice crystals in an engine ground test environment.

Eric Duvivier 




A graduate from Paris Aerospace Engineering School in 1998, 

Mr. Duvivier started in 1989 at French Ministry of Defence 

working as Environmental Control System (ECS) specialist 

on military programs. In 1991, he joined the airworthiness 

department of the French Direction de l’Aviation Civile in Paris, 

as ECS and Icing specialist, working certification and rule making issues. Since 

1992, Mr. Duvivier has been highly involved for the Joint Aviation Authorities in 

certification programs and harmonisation of the JAR 25 with the FAR 25 icing and 

ECS related requirements. In that respect, he was a member of the Ice Protection 

Harmonisation Working Group (IPHWG) and Mechanical Systems HWG. In 1999, he 

was nominated by the JAA as Certification Standardisation Panel, acting in the JAA 

system, as co-ordinator and advisor for conflicting certification issues. Mr. Duvivier 

joined the European Aviation Safety Agency (EASA) as ECS and Icing expert in the 

Certification Directorate in September, 2004 and has since been nominated in the 

Panel of Experts of EASA to ensure that there is a consistent interpretation and 

application of requirements by EASA Teams following EASA Procedures 

“Operational Issues in Icing” 

This presentation is a short description of the organization of EASA. It 

will explain how future rules will be generated in Europe. The current 

subjects under discussion and the plan for the next five years in the 

field of ground icing and in flight icing will also 

be included.

Wayne Chapin 

Chief Certification and Operational Standard 

Commercial and Business Aviation 

Transport Canada 

MONDAY 

Wayne Chapin’s aviation career started in 1971 after he graduated 

from University with a degree in Business Administration and 

Economics. Wayne flew a variety of small and large aircraft on 

wheels, floats and skis as a “bush pilot” including C185, DHC3, 

Grumman Goose, DHC6 and the venerable DC3. Wayne is type 

rated on the DC3, C550 and the Bombardier Regional Jet Series 200/700/705 and 900. 

Wayne started as a Transport Canada Civil Aviation Inspector in 1988 and has worked 

in various positions in Air Navigation System Requirements, Air Navigation System and 

Airspace, Commercial and Business Aviation and the new Standards Branch where is he 

currently the Chief of Certification and Operational Standards. 

“Transport Canada’s Perspective on Operations under Icing Conditions” 

This keynote address will provide a historical backdrop for the current regulations in place today with a focus on 

understanding and assessing why icing related accidents continue to occur and what further mitigation strategies 

are required to minimize future icing related accidents. 

In large part due to Canada’s geographic location and weather, operations under icing conditions, either on the 

ground or in the air are almost a year round possibility. Hence Canadians have had to deal with and develop 

essential strategies to cope with this unending environmental risk. 

Every year in Canada, thousands of aircrafts are prepared for flight during adverse winter weather conditions. For 

example, the Toronto and Montreal Central Deicing Facilities, which are the two largest in Canada, alone de/antiice 

approximately 20,000 aircraft every winter. These include aircraft from medium sized single engine turbopropeller 

aircraft to the largest turbojet transport category aircraft. 

Transport Canada is responsible for icing regulations covering the operation of all aircraft in Canada including 

foreign air operators. Transport Canada regulations as well as regulations from other authorities in this area have 

evolved over the past 20 years, mostly as a result of significant accidents. Transport Canada and other aviation 

authorities have spent upwards of 25 million dollars in research money over the past 15 years, to foster further 

knowledge, update regulations and improve safety for operations during inclement weather.

12:15 – 13:00 

Peter Devaris 

Safety Analysis Branch Manager 

Office of Accident Investigation 


Mr. Devaris is with the Federal Aviation Administration serving 

as the Safety Analysis Branch Manager and Senior Analyst 

within the Office of Accident Investigation. He is involved in 

the Cessna 208 Icing Accident Work Group and served as 

Co-Chair of the Government Liaison Committee. Mr. Devaris 

is an instructor and Team Lead for TapRoot® Root Cause Analysis, a Re-write 

Team Member for the FAA Advisory Circular AC 91-74, Pilot Guide to Flight in Icing 

Conditions, and served as the Flight Standards Lead for Mitsubishi MU-2 Safety 

Evaluation. In 2004, Mr. Devaris was named the Flight Standards National Field 

Inspector of the Year for his contributions and hard work. Because of his work 

with the CE208, MU-2, and dedication to improving aviation safety, Mr. Devaris 

was selected as the 2007 recipient of the Regional Air Cargo Carriers Association’s 

Excellence in Government Award. His extensive operational experience and 

involvement in the aircraft and engine icing has made significant contributions to 

aviation safety. 

“From Engineering to Operations: Narrowing the informational and educational divides 

between aircraft icing engineering, testing, certification, and their applications in 

actual operations.” 

This presentation will discuss the interrelationships between airframe testing and certification and 

its application during aircraft operations. Recent research and accident investigations indicate that 

a better understanding by pilots of icing testing and certification can improve operational safety. 

Conversely, icing engineers and certification teams can also help improve operational safety through 

a better understanding of what information is presented to pilots during training and how that impacts 

the safety of their daily operations. 

The presentation will focus on lessons that engineers and pilots can learn from each other including: 

• AFM content and its use as an informational vs. regulatory tool 

• Critical ice shape recognition 

• Visual vs. performance cues 

• High performance booted singles 

• Case study of pilot icing information knowledge 

• SLD detection, recognition, and avoidance 

• King Air-Rawlins, WY 

• Stall recovery during aircraft certification versus pilot certification 

• Icing Terminology and Definition Creep 

• Educational opportunities for improving information exchange 

• Practical Test Standards 

• AC 91-74 

• MU-2 SFAR vs. CE-208 Icing Training (regulatory alternative)
