Airworthiness Directive · Amendment 39-15119 · Wings
Alpha Aviation Design Limited (Type Certificate No. A48EU Previously Held by APEX Aircraft and AVIONS PIERRE ROBIN) Model R2160 Airplanes
This AD applies to Model R2160 airplanes, serial numbers 001 through 378, 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:
Unless already done, do the following actions (Accomplishment of European Aviation Safety Agency (EASA) AD 2005-0028 satisfies the requirement of this AD):
(1) Initially within 60 months after aircraft date of manufacture or within 6 months after August 10, 2007 (the effective date of this AD), whichever occurs later, and thereafter at intervals not to exceed 24 months, remove the main landing gear legs and all the wing inspection panels following the instructions in the aircraft maintenance manual and inspect the visible parts of the spar web and the upper and lower boom angles (top and bottom spar caps), following Avions Pierre Robin Service Letter No. 19, dated October 1980; and Avions Pierre Robin Service Bulletin No. 99, dated June 24, 1983. If the spars are replaced, then you must inspect within 60 months from the date of replacement and thereafter every 24 months.
(i) If, during any inspection required by paragraph (f)(1) of this AD, any sign of corrosion is found on the rear face of the spar web or the upper and lower boom angles, then inspect the front face of the spar for corrosion following Avions Pierre Robin Service Letter No. 19, dated October 1980; and Avions Pierre Robin Service Bulletin No. 99, dated June 24, 1983. It may be necessary to cut inspection holes or remove the wings to inspect the front face of the spar. Inspection holes must be prepared to a manufacturer-approved repair scheme.
(ii) If corrosion is found during any inspection required by this AD that does not exceed the limits specified in Avions Pierre Robin Service Letter No. 19, dated October 1980, treat the corrosion following Avions Pierre Robin Service Letter No. 19, dated October 1980; and Avions Pierre Robin Service Bulletin No. 99, dated June 24, 1983.
(2) If corrosion is found during any inspection required by this AD that exceeds the limits specified in Avions Pierre Robin Service Letter No. 19, dated October 1980, before further flight from when the corrosion is found that exceeds the limits:
(i) Obtain an FAA-approved repair scheme from the manufacturer; and
(ii) incorporate this repair scheme.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
