21.A.14(b) 21.A.143, 21.A.243, Flight Test Operations Manual (FTOM)
21.A.14(b), 21.A.112B(b) and 1. General
21.A.432B(b) AMC
a. Scope: The FTOM covers flight test operations.
The FTOM complexity should be proportionate to the aircraft and the organisation
complexity.
b. Format
The FTOM may:
- be included in the Design Organisation Approval (DOA)/Production
Organisation Approval (POA)/Alternative Procedure to DOA (APDOA)
documents, or
- be a separate manual.
The FTOM may make reference to other documents to cover the contents listed
below, e.g. for recordkeeping.
c. Use by contractors or sub-contractors:
When flight tests are performed by contractors or subcontractors, they should
comply with the FTOM of the primary organisations, unless they have established an
FTOM in compliance with Part21, the use of which has been agreed between the
two organisations.
2. The FTOM should contain the following elements:
a. Exposition (not applicable in the case of APDOA):
If the FTOM is presented as a separate document, it should include a chart
indicating the structure of the organisation and, more specifically, the functional links
of the people in charge of flight test activities. It should also mention the coordination
between all departments affecting flight test, e.g. Design Office, Production and
Maintenance, in particular coordination for the establishment and update of a Flight
Test Programme.
b. Risk and safety management:
The FTOM should describe the organisation’s policy in relation to risk and safety
assessment, mitigation and associated methodologies.
c. Crew members:
According to the flight test category, the FTOM should describe the organisation’s
policy on the composition of the crew (including the need to use a Lead Flight Test
