## EASA AIRWORTHINESS DIRECTIVE

AD No.: 2010-0090

Date: 18 May 2010

Note: This Airworthiness Directive (AD) is issued b y EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the Europe an Community, its Member States and of the European third countries that participate in th e activities of EASA under Article 66 of that Regulation.

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be en sured by accomplishing any applicable ADs. Conseque ntly, no person may operate an aircraft to which an AD applies, except in accor dance with the requirements of that AD, unless othe rwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/200 8, Article 14(4) exemption].

### ATA 35 Oxygen - Chemical Oxygen Generator - Modific ation

Manufacturer(s): SOCATA (formerly EADS SOCATA)

Applicability: TBM 700A and TBM700B aeroplanes, s/n 1 to 204, 206 to 239 and 241 to 243 included, equipped with chemical oxygen system (B/E Aerospace, formerly Puritan Bennett).
Note: For this system, the oxygen masks at front se ats are located under R.H. station seat.

Reason: During a SOCATA flight test, it was noted some diff iculties for the pilot to release oxygen. After investigation it was found th at, due to the design of the oxygen generator release pin, one of the mask’s lan yard linked to the pin could be jammed when it is pulled by a pilot or a p assenger.
This condition, if not corrected, would lead, in ca se of an emergency procedure due to decompression, to a risk of genera tor fault with subsequent lack of oxygen on crew and/or passenger.

For the reason described above, SOCATA released Pil ot Operating Handbook (POH) Temporary Revision (TR) 03 which asks, in cas e of failure to release oxygen, to pull on the other mask lanyard in order to activate the oxygen generator. The Emergency AD 2009-0096-E was issued to mandate the follow-up of these actions by the operators in case of failure. This EAD was subsequently revised into AD 2009-0096R1 in order t o clarify the applicability.
A SOCATA modification enabling to solve this issue has been developed. Consequently, this new AD, superseding EASA AD 2009 -0096R1 retaining its requirements, requires implementing the modificatio n which is a terminating action.EASA AD No : 2010-0090

EASA Form 110 Page 2/2 Effective Date: 01 June 2010

Required Action(s) and Compliance Time(s): Required as indicated, unless already accomplished:
(1) Before next flight after 23 April 2009 (effecti ve date of EASA AD 2009- 0096R1), revise the procedure “Oxygen Use” in para graph 3.13 of the Pilot Operating Handbook (POH) to include the follo wing statement:

IN CASE OXYGEN GENERATOR FAILS TO ACTIVATE

PULL ON THE OTHER LANYARD

Inserting a copy of this AD into the POH is an acce ptable means to comply with the requirement of paragraph (1) of thi s AD.

(2) Upon reception of Temporary Revision (TR) 03 to TBM700 A and B Pilot’s Operating Handbook (POH), insert the TR 03 into the POH and remove the AD from the Operating Handbook.
Note: Before every flight, it is the crew responsib ility to warn passengers of the way to properly activate oxygen generator.

(3) Within 7 months or 100 Flight Hours after the e ffective date of this AD, whichever occurs first, replace the existing oxygen generator release pin with an open pin P/N T700A351004410000, in accordan ce with the accomplishment instructions of SB No.70-168-35 init ial issue.
(4) Upon replacement of the existing oxygen generat or release pin with an open pin P/N T700A351004410000, in accordance with the accomplishment instructions of SB No.70-168-35, rem ove the change as introduced by paragraph (1) and remove EASA AD 2009 -0096R1 from the Operating Handbook.
(5) After the effective date of this AD, do not ins tall in an aeroplane any oxygen generator release pin P/N T700A3510038100.
