DAHER AEROSPACE (TYPE CERTIFICATE PREVIOUSLY HELD BY
Amendment 39-21834; Docket No. FAA-2021-0778; Project Identifier 2019-CE-062-AD.
(a) EFFECTIVE DATE This airworthiness directive (AD) is effective January 12, 2022. (b) AFFECTED ADS None. (c) APPLICABILITY This AD applies to Daher Aerospace (type certificate previously held by SOCATA) Model TBM 700 airplanes, serial numbers 1106 and larger, certificated in any category. (d) SUBJECT Joint Aircraft System Component (JASC) Code 2130, Cabin Pressure Con- trol System. (e) UNSAFE CONDITION This AD was prompted by mandatory continuing airworthiness information (MCAI) originated 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 a non-conforming dump switch ejecting from its slot. The FAA is issuing this AD to prevent dump switches ejecting from their slots, which, in case of smoke/fumes in the cabin, could prevent evacuation of the smoke/fumes. The unsafe condition, if not addressed, could result in excessive flight crew workload and injury to airplane occupants. (f) COMPLIANCE Comply with this AD within the compliance times specified, unless al- ready done. (g) REQUIRED ACTIONS Within 12 months after the effective date of this AD, inspect each dump switch part number (P/N) 7388475012 to determine if a seal is installed, as depicted in Figure 3 of Daher Aerospace Service Bulletin SB 70-271-21, Revision 1, dated November 2019. (1) If a seal is installed, no further action is required by this para- graph. (2) If a seal is not installed, within 12 months after the effective date of this AD, modify the dump switch in accordance with steps (2) through (5) of the Description of Accomplishment Instructions in Daher Aerospace Service Bulletin SB 70-271-21, Revision 1, dated November 2019. (h) PARTS INSTALLATION PROVISION As of the effective date of this AD, do not install a dump switch P/N 7388475012 on any airplane unless the switch has been modified as de- scribed in Daher Aerospace Service Bulletin SB 70-271-21, Revision 1, dated November 2019. Removal of a dump switch from an airplane and re- installation of that dump switch on the same airplane within the same maintenance visit is not an installation for purposes of this para- graph.
