Airworthiness Directive · Amendment 39-15729 · Power plant
Diamond Aircraft Industries GmbH Model DA 42 Airplanes
This AD applies to Model DA 42 airplanes, all serial numbers, certificated in any category, that have Thielert TAE125-01 engines installed, except those airplanes with engines identified by serial number in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-058, dated May 21, 2008, that have been installed on the aircraft with wedge locking washers and bonded-in bolts and are therefore not affected by this AD.
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:
(1) Within the next 100 hours time-in-service (TIS) after December 22, 2008 (the effective date of this AD) and repetitively thereafter at intervals not to exceed 100 hours TIS, do the inspection and correction of the fastening torque of the RH rear engine support bracket mounting bolts following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-058, dated May 21, 2008; and Action 1 of Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-058, dated March 12, 2008.
(2) Within 6 months after December 22, 2008 (the effective date of this AD), replace all RH rear engine support bracket mounting bolts with wire-secured bolts, P/N D60-9071-26-01, following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-058, dated May 21, 2008; and Action 2 of Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-058, dated March 12, 2008.
(3) Installation of the wire-secured bolts, P/N D60-9071-26-01, as required by paragraph (f)(2) of this AD, terminates the repetitive torque inspections required by paragraph (f)(1) of this AD.
(4) As of 6 months after December 22, 2008 (the effective date of this AD), no person shall install spare RH rear engine support bracket mounting bolts as replacement parts on any aircraft to which this AD applies, except P/N D60-9071-26-01 wire-secured bolts.
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.
