AD 2015-26-09 Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Models named: ATR42-200, -300, -320, -500. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all ATR—GIE Avions de Transport Régional (ATR) Model ATR42-200, -300, -320, and -500 airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(1) For all Model ATR42 airplanes: At the later of the compliance times specified in paragraphs (g)(1)(i) and (g)(1)(ii) of this AD, and thereafter at intervals not to exceed 12,000 flight cycles, accomplish a detailed inspection for damage (cracks, corrosion, dents, scratches, scores and abrasions) of the floor beam at FR 26, on the left-hand (LH) and right-hand (RH) sides, in accordance with the instructions of ATR Job Instruction Card 535100 DVI 10097, “DVI of FR26 Floor Beam Around Cut-outs for Cooling & Hydrau Ducts,” dated February 9, 2012 (for Model ATR42-200, -300, -320, and -500 airplanes). (i) Before the accumulation of 24,000 total flight cycles. (ii) Within 5,000 flight hours or 24 months, whichever occurs first, after the effective date of this AD. (2) If, during any inspection required by paragraph (g)(1) of this AD, any damage (corrosion or scratches that are greater than allowed, cracks, dents, scores and abrasions) is found: Before further flight, repair in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or ATR—GIE Avions de Transport Régional's EASA Design Organization Approval (DOA).
Unsafe condition
This AD was prompted by several reports of a cracked floor beam at frame (FR) 26 on several Model ATR42 airplanes, and of discrepancies in certain wing inspection tasks in maintenance documents that could lead to errors in scheduling inspection intervals of structurally significant items (SSIs). We are issuing this AD to detect and correct any cracking of the floor beam at FR 26 and several areas of the wings, which could lead to reduced structural integrity of the airplane.
Affected ADs
None.
