4.2 IIC Duties for Work Planning
The purpose of the work planning meetings is to discuss activities that will follow
the on-scene phase of investigation (e.g., component teardowns, followup interviews, etc.). It also
allows all involved staff to agree on realistic schedules to complete required work products. Refer to
Board Order 70 for detailed requirements.
The IIC shall prepare a memo announcing the meeting, its location, date, and time.
The memo should be accompanied by a summary outlining the major issues of the investigation and
distributed to each group chairman, his or her supervisor, and the respective Office Directors and
Deputy Directors several days before the meeting.
The IIC should anticipate the investigative activities that each group chairman should
pursue and suggest avenues for followup investigation, if necessary. By the end of the meeting, the
group chairmen and managers should agree to the accident-related issues, the general activities that
remain, the type of report to be generated, the recommendation on whether to convene a public
hearing, and the deadlines for the factual and analysis reports. Report completion deadlines may
need to be negotiated with the group chairmen and their supervisors depending on their workloads
and priorities. The Office Directors or their Deputies will resolve any conflicts regarding deadlines.
The IIC will prepare a memo summarizing items of agreement achieved during the
meeting, a revised issue outline, and any unresolved issues. All deadlines for report submissions and
anticipated milestones should be included. The memo should be distributed to each group chairman,
his or her supervisor, the respective Office Directors and Deputy Directors, and the Managing
Director.
The IIC will maintain contact with the group chairmen during the course of the
investigation and be aware of the progress of their followup activities. The group chairmen will
notify the IIC if they can not meet report deadlines and provide a new date for completion of their
reports. The IIC will integrate the activities of related investigative groups if it is determined that
they are proceeding in similar directions. For example, if maintenance training becomes an issue,
the systems, maintenance records, and structures groups might examine maintenance practices
together. Likewise, the human performance and the operations groups may work together in
carrying out interviews and records examinations. If two group chairmen are working together, the
IIC should ensure that each of them will cover a specific area to avoid overlap among the groups.
Identical areas of investigation should not appear in the reports of two separate groups.
The IIC should ensure that he or she is informed of all group activities and group
findings. The IIC is responsible for ensuring that the appropriate group chairman will cover all
relevant issues. The IIC is also responsible for keeping abreast of potential discrepancies, loopholes
