Starter distress
Forrest Holly, Tucson, Arizona
My IO-520B has signs of starter distress. Over the past
Q: 10 starts, I first noticed occasionally a new hard clunk
as the starter first engaged. In subsequent starts there was
an occasional “stall” as the starter tried to rotate the engine
but couldn’t (okay after I released the switch and tried
again). Then today it gave a kind of shudder or rapid skipping,
followed by a fairly normal engagement and start but
with some shudder. This feels like a mechanical and not
an electrical issue to me; the battery is about a year old
and there are no other signs of electrical or mechanical
issues once I’ve started up.
The starter was rebuilt about 350 hours ago, and the
engine has about 600 hours on it (field overhaul of a factory
reman). I’m going to get my mechanic to have a look at it
later in the week, but thought I would run this by you to see
if tells you something that would be useful for the mechanic
(and me) to know.
The most probable cause of your problem is the starter
A: adapter. This problem seems to me more prevalent with
15/50W oil. The best action is to replace the complete adapter
with a rebuilt unit from Niagara Air Parts (800-525-4268). They
hold an STC to beef up the original Continental adapter. —BR

ADs and inspections
Paul Gilbert, Bloomsburg, Pennsylvania
My plane is going for its annual inspection and I was
Q: wondering if there is a checklist of the Airworthiness
Directives, and a maintenance checklist, on the ABS website?
Because Beech airplanes are among the most
A: potentially modified of all types, there is no one
list of Airworthiness Directives that applies to them all.
It takes a little sleuthing to come up with the list that
applies to a specific aircraft. These items are on the Technical
Resources page for your A36, on the ABS website:
The first link on the Technical Resources page is to the
Annual/100-Hour Inspection Checklist for your Bonanza. It is
from the maintenance manual for your airplane, which your
mechanic should have in order to conduct the inspection.
He/she may supplement the manufacturer’s data with these
ABS Air Safety Foundation Maintenance Guides, also found
under Maintenance & Operation on the website:
Flight Controls, Flaps Trim System Inspection, Repair
and Rigging Guide

Q:
A:
Drag brace
Robert Baskins, Huntington Beach, California
Will a 1974 E55 nose gear drag brace fit a 1974
V35B?
Depending on the installed equipment of the Baron,
yes, the drag brace assembly is interchangeable.
Based on serial number applicability for the V35B you
provided, the proper part number for the drag brace is
95-824019-3. This is a welded steel tubular drag brace. A
1974 E55 Baron has a serial range from TE-971 to TE-1014.
During this time, either a 95-824019-3 (welded steel tube)
or a 002-820016-321 (cast aluminum) drag brace could
have been installed. You will need to make sure you get
the correct part when you are looking and please be
sure to replace the drag brace and the lower drag leg as
a matched assembly. —CB
