(1) Deployment Scenarios:
(i) structural failure
(ii) mid-air collision
(iii) stall/spin
(iv) loss of control/icing
(v) engine failure over bad terrain
(vi) pilot incapacitation
(2) Installation Considerations: The
builder should consider the following when installing
a ballistic chute:
(i) Matching the chute with the aircraft’s
size, weight, and Vne speed (check with the
chute manufacturer)
(ii) How the chute will be positioned
and mounted
(iii) The chute’s effect on the aircraft’s
weight and balance before deployment and
aircraft’s touchdown attitude after deployment
(iv) Compatibility of the opening
loads and the aircraft’s structural design limits

(v) The routing of the bridle and
harness
(vi) The routing of the activating
housing
(vii) The placement of the activating
handle in the cockpit
(viii) Incorporation of chute deployment
procedures in the in-flight emergency plan and
emergency check list
(ix) The deployment time, from
activation to full chute opening
(3) If a ballistic chute is installed, the
builder should add the appropriate ballistic chute
inspection items to the aircraft’s pre-flight inspection
check list. The builder also should add the
ballistic chute manufacturer’s repack/refitting schedule
and maintenance inspections to the flight manual
and the conditional annual inspection check list.
SECTION 4. TEST PILOT
‘‘We are looking for a few good Men and Women!’’ Marine Corps advertisement (1991)
1. OBJECTIVE. To select a qualified individual
to be the test pilot.
2. GENERAL. The test pilot should be competent
in an aircraft of similar configuration, size,
weight, and performance as the aircraft to be tested.
If the aircraft’s builder is the test pilot, the costs
involved in maintaining pilot competence should be
budgeted with the same level of commitment and
priority that is assigned to plans and materials to
complete the project.
3. TEST PILOT REQUIREMENTS.
a. A test pilot should meet the following minimum
qualifications:
(1) Physically fit: Test flying an aircraft is
a stressful and strenuous task
(2) No alcohol or drugs in the last 24 hours
(3) Rated, current, and competent in the
same category and class as the aircraft being tested
(4) Current medical and biennial or flight
review as appropriate, or a current USUA certification
and flight review
b. Suggested Test Pilot Flight Time Requirements.
The following suggested number of flight
hours are only an indication of pilot skill, not an
indicator of pilot competence. Each test pilot must
assess if their level of competence is adequate or
if additional flight training is necessary. If an individual
determines they are not qualified to flight test
an unproven aircraft, someone who is qualified must
be found.
(1) 100 hours solo time before flight testing
a kit plane or an aircraft built from a time-proven
set of plans
(2) 200 hours solo time before flight testing
for a ‘‘one of a kind’’ or a high performance
aircraft
(3) A minimum of 50 recent takeoffs and
landings in a conventional (tail wheel aircraft) if the
aircraft to be tested is a tail dragger
c. The test pilot should:
(1) Be familiar with the airport and the
emergency fields in the area
(2) Talk with and, if possible, fly with a
pilot in the same kind of aircraft to be tested
(3) Take additional instruction in similar
type certificated aircraft. For example, if the aircraft
to be tested is a tail dragger, a Bellanca Citabria
or Super Cub is appropriate for training. For testing
an aircraft with a short wing span, the Grumman
American Yankee or Globe Swift is suitable for
training.
(4) Be considered competent when they
have demonstrated a high level of skill in all planned
flight test maneuvers in an aircraft with performance
characteristics similar to the test aircraft

5/24/95 AC 90-89A
(5) Study the ground and in-flight emergency
procedures developed for the aircraft and practice
them in aircraft with similar flight characteristics
(6) Have logged a minimum of 1 hour of
training in recovery from unusual attitudes within
45 days of the first test flight
(7) If appropriate, have logged a minimum
of 10 tail wheel take-off and landings within the past
30 days
(8) Study the performance characteristics
of the aircraft to be tested. Refer to the designer’s
