Aerospatiale Model ATR42-300, -300, and -320 Series Airplanes
Superseded. A later AD replaced this one: AD 2020-09-16. Comply with the one in force.
All Model ATR42-200, ATR42-300, and ATR42-320 series airplanes, certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to all Aerospatiale Model ATR42-200, -300, and -320 series airplanes, that requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate life limits for certain items and inspections to detect fatigue cracking in certain structures. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to ensure that fatigue cracking of certain structural elements is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
To ensure continued structural integrity of these airplanes, accomplish the following:
(a) Within 30 days after the effective date of this AD, revise the Airworthiness Limitations Section of the Instructions for Continued Airworthiness by incorporating the “Time Limits” section of the ATR42-200/-300/-320 Maintenance Planning Document, Revision 4, dated July 1999, into the Airworthiness Limitations Section.
(b) Except as provided in paragraph (c) of this AD: After the actions specified in paragraph (a) of this AD have been accomplished, no alternative inspections or inspection intervals may be approved for the structural elements specified in the document listed in paragraph (a) of this AD.
