specific clearance and flight testing of your aircraft. This will require checking and
returning to the BMAA for an authorisation signature to make it valid.
Initially your aircraft must be flown by a BMAA Test Pilot, or a specially authorised
check pilot. He/She will fly the aircraft to the flight test schedule to ensure that your
aircraft is set up and flying as it should. You can accompany them for the flight tests
as observer / secretary. When the aircraft is flying satisfactorily (some trimming /
adjustments may be required), then if you have suitable experience you may fly the
aircraft. 5 hours of flying are required to prove reliability and debug the aircraft,
before an application can be made for a full permit to fly. Whilst waiting for this to
arrive you are normally permitted to fly the aircraft, continuing to obey the restrictions
of the test flying clearance contained in the AW029.
If you are the first with a new engine or propeller type, or have made any major
modifications to your aircraft, then 25 hours of reliability testing are usually required.
If you plan any modifications then it is essential that the BMAA is informed at the
beginning of the project, so that a technical investigation can be made and approval
for you to go ahead can be given.
It is likely that you are keen to begin construction, and are waiting impatiently for the
paperwork and your inspector to allow you to do so. However, this short delay can be
used very productively to familiarise yourself with the instructions and the
components, and prepare them for use.
Modifications
You may desire to install equipment such as a radio, strobes etc.. These will
constitute modifications to the standard aircraft and therefore must be done in
accordance with BMAA procedures. Details of the most common modifications are
included in the TIL’s, and Standard Minor Mods (SMM) available on the BMAA
website (
www.bmaa.org ) . If these are done at the time of construction no additional
modification fees are payable.
For modifications not covered by the TIL’s, or SMM’s, it is probably better to
complete the standard aircraft and commence flying before proceeding with the
modification. This is because non-standard modifications will introduce complexity
and delays into getting you aircraft flying, and so these are best done at leisure when
you already have your aircraft in the air.
Note that the Nynja succeeds in providing a capable aeroplane at an excellent price
by following the principle of simplicity. Some areas may look basic at first glance, but
meet the stringent requirements of BCAR Section S without adding cost and weight.
Any modifications you make must also meet Section S, but it is up to you how much
cost you are willing to bear and where you spend your weight. However, increased
cost and less fuel carrying capacity are difficult to avoid.
Do not begin any modifications without first speaking to your inspector, the
BMAA, or Flylight Airsports.
