AD 2009-18-18 Airworthiness Directives; ATR Model ATR42 and ATR72 Airplanes

Models named: ATR42-200, -300, -320, -500, ATR72-101, -201, -102, -202, -211, -212. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to ATR Model ATR42-200, -300, -320, and -500 airplanes and Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes; certificated in any category; that are equipped with any PPG Aerospace cockpit forward side glass window having part number (P/N) NP-158862-1 or NP-158862-2.

Unless already done, do the following actions. (1) Prior to the accumulation of 2,000 total flight cycles on any cockpit forward side window, or within 10 days after the effective date of this AD, whichever occurs later, inspect for damage and absence of repair of the cockpit forward side windows, in accordance with the Accomplishment Instructions of PPG Aerospace Service Bulletin NP-158862-001, dated July 8, 2009. If the total flight cycles on a given cockpit forward side window installed on an airplane cannot be established, the total flight cycles accumulated on the airplane must be used in determining the initial inspection time for the cockpit forward side window. (i) If any discrepant condition, as defined in PPG Aerospace Service Bulletin NP-158862-001, dated July 8, 2009, is found: Replace the window, in accordance with a method approved by the Manager, ANM-116, International Branch, Transport Airplane Directorate, FAA, or EASA (or its delegated agent), before further pressurized flight or within 10 days after the inspection, whichever occurs first. Note 1: Guidance on replacing windows may be found in ATR (ATR42) Aircraft Maintenance Manual (AMM) Job Instruction Card (JIC) 56-12-00 RAI 10000-011, dated February 2008; and ATR ATR72 AMM JIC 56-12-00 RAI 10000-001, dated April 2008. Note 2: Guidance on unpressurized flight conditions and limitations may be found in Section 21-30-1, dated February 2008, of the ATR Master Minimum Equipment List; and Section 21-30-1, dated February 2008, of the ATR Dispatch Deviation Guide. (ii) If one of the conditions identified in paragraphs (f)(1)(ii)(a), (f)(1)(ii)(b), and (f)(1)(ii)(c) of this AD is found: Within 50 flight cycles or 7 days after the inspection required by paragraph (f)(1) of this AD, whichever occurs later, repeat the inspection required in paragraph (f)(1) of this AD. Re-inspect at intervals not to exceed 50 flight cycles or 7 days, whichever occurs later. When any discrepant condition, as defined in PPG Aerospace Service Bulletin NP-158862-001, dated July 8, 2009, is found: Replace the window, in accordance with a method approved by the Manager, ANM-116, International Branch, Transport Airplane Directorate, FAA, or EASA (or its delegated agent), before further pressurized flight or within 10 days after the inspection, whichever occurs first. (a) Sealant separation between the Z-bar and the outer glass ply, with depth less than or equal to 4 mm (0.160 in). (b) Sealant separation between inboard retainer and inner glass ply, with depth less than or equal to 7.5 mm (0.300 in) and cumulative length less than or equal to 300 mm (12.000 in). (c) Window showing both sealant separation between the Z-bar and the outer ply, and separation between inboard retainer and inner glass ply, common to the same hole location with a length less than or equal to 225 mm (8.860 in), and not covering the entire arc of a window corner. (iii) If no discrepancy is found: Re-inspect the cockpit forward side windows at intervals not to exceed 550 flight hours, in accordance with the Accomplishment Instructions of PPG Aerospace Service Bulletin NP-158862-001, dated July 8, 2009. When any discrepant condition, as defined in PPG Aerospace Service Bulletin NP-158862-001, dated July 8, 2009, is found: Replace the window, in accordance with a method approved by the Manager, ANM-116, International Branch, Transport Airplane Directorate, FAA, or EASA (or its delegated agent), before further pressurized flight or within 10 days after the inspection, whichever occurs first. (2) Within 30 days after any inspection when damage or a discrepancy is found or within 30 days after the effective date of this AD, whichever occurs later, submit a detailed report of the findings to ATR in accordance with PPG Aerospace Service Bulletin NP-158862-001, dated July 8, 2009.
