Diamond Aircraft Industries GmbH Airplanes With Supplemental Type Certificate (STC) SA03674AT
This AD applies to Diamond Aircraft Industries GmbH Model DA 40 airplanes, all serial numbers, that:
(1) Are equipped with vapor cycle system (VCS) cabin air conditioning installed per Premier Aircraft Service STC SA03674AT following DER Services Master Document List MDL-2006-020-1, Revision C, dated February 3, 2009; Revision D, dated April 22, 2009; Revision E, dated May 12, 2010; or Revision F, dated July 6, 2010; and

We are adopting a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Model (Diamond) DA 40 airplanes equipped with cabin air conditioning vapor cycle system (VCS) installed per STC SA03674AT held by Premier Aircraft Services (originally held by DER Services, Inc.) following DER Services Master Document List MDL-2006- 020-1, Revision C, dated February 3, 2009; Revision D, dated April 22, 2009; Revision E, dated May 12, 2010; or Revision F, dated July 6, 2010. This AD was prompted by reports of damage around the VCS compressor mounting areas found during maintenance inspections. This AD requires deactivation of the VCS, removal of the compressor and bracket, and revision to the airplane weight and balance. We are issuing this AD to correct the unsafe condition on these products.
Within the next 100 hours time-in-service after installation of the VCS installed per STC SA03674AT held by Premier Aircraft Service (originally held by DER Services, Inc.) following DER Services Master Document List MDL-2006-020-1, Revision C, dated February 3, 2009; Revision D, dated April 22, 2009; Revision E, dated May 12, 2010; or Revision F, dated July 6, 2010, or within 30 days after November 16, 2011 (the effective date of this AD), whichever occurs later, do the following actions following Premier Aircraft Service Work Instruction PAS-WI-MSB-40-2011-001, dated March 4, 2011; and Premier Aircraft Service Mandatory Service Bulletin No. PAS-MSB-40-2011-001, dated March 4, 2011:
(1) Deactivate the VCS system.
(2) Pull and collar the compressor breaker and place a placard above the breaker stating “INOP.”
(3) Remove the VCS compressor and associated mounting hardware.
(4) Revise the airplane weight and balance.
If all actions in paragraphs (g)(1), (g)(2), (g)(3), and (g)(4) of this AD have been completed, an optional terminating action allows you to reinstall the VCS compressor and reactivate the air conditioning system following Premier Aircraft Service Service Bulletin No. PAS-SB-40-2011-002, dated August 18, 2011; Seamech International Inc. Vapor Cycle Air Conditioning with Automatic Climate Control Instructions for Continued Airworthiness, ASI-772216A, Revision G, dated August 9, 2011; Seamech International Inc.
