Airworthiness Directive · Amendment 39-15556 · Power plant-general
GENERAL AVIA Costruzioni Aeronatiche Models F22B, F22C, and F22R Airplanes
This AD applies to Models F22B, F22C, and F22R airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Do the following actions:
(1) Unless already done within the last 100 hours time-in-service (TIS) before July 23, 2008 (the effective date of this AD), before further flight and repetitively thereafter at intervals not to exceed 100 hours TIS, inspect the structure surrounding the heads of the four bolts of the engine mount attachment bracket, approaching from the cabin of the aircraft in the zone below the instrument panel. In case the indicated area (in particular for the upper bolts) is not visible due to equipment presence (relay, cooling fan, and so forth), remove all of the upper right-hand panel and part of the left-hand panel of the fireproof bulkhead to approach the area to be inspected through the engine compartment. In this case the use of a small mirror is necessary.
(2) If as a result of any inspection required by paragraphs (f)(1) of this AD you find any discrepancies (for example, cracked or broken parts), do one of the following actions before further flight:
(i) Repair the aircraft following Gomolzig Flugzeug-und Maschinenbau GmbH General Avia F22 Modification 15328 Repair Instructions, dated September 10, 2007; or
(ii) Repair the aircraft following a repair method approved by the FAA for this AD.
(3) If you repair the aircraft as specified in paragraph (f)(2)(i) of this AD, repetitively thereafter inspect the aircraft at intervals not to exceed 500 hours TIS following the instructions in paragraph (f)(1) of this AD. If as a result of these repetitive inspections you find any discrepancies, prior to further flight, repair the aircraft following Gomolzig Flugzeug-und Maschinenbau GmbH General Avia F22 Modification 15328 Repair Instructions, dated September 10, 2007.
(4) If you repair the aircraft as specified in paragraph (f)(2)(ii) of this AD, repetitively thereafter inspect the aircraft using the repetitive inspection interval established by the FAA-approved repair method used. Follow the inspection instruction in paragraph (f)(1) of this AD. If as a result of the inspection you find any discrepancies, repair before further flight following a repair method approved by the FAA for this AD.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
