EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0090 

Date: 18 May 2010 

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of 

the European third countries that participate in the 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 ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency 

[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption]. 

Type Approval Holder’s Name : 

SOCATA

Type/Model designation(s) : 

TBM 700 aeroplanes 

TCDS Number : EASA A.010 

Foreign AD : Not applicable 

Supersedure : This AD supersedes EASA AD 2009-0096R1 dated 10 July 2009 

ATA 35 Oxygen - Chemical Oxygen Generator - Modification 

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 seats are located under R.H. 

station seat. 

Reason: 

During a SOCATA flight test, it was noted some difficulties for the pilot to 

release oxygen. After investigation it was found that, due to the design of the 

oxygen generator release pin, one of the mask’s lanyard linked to the pin 

could be jammed when it is pulled by a pilot or a passenger. 

This condition, if not corrected, would lead, in case of an emergency 

procedure due to decompression, to a risk of generator fault with subsequent 

lack of oxygen on crew and/or passenger. 

For the reason described above, SOCATA released Pilot Operating Handbook 

(POH) Temporary Revision (TR) 03 which asks, in case 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 to 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 modification which is a terminating 

action.

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 (effective date of EASA AD 2009-

0096R1), revise the procedure “Oxygen Use” in paragraph 3.13 of the 

Pilot Operating Handbook (POH) to include the following statement: 

IN CASE OXYGEN GENERATOR FAILS TO ACTIVATE 

PULL ON THE OTHER LANYARD 

Inserting a copy of this AD into the POH is an acceptable means to 

comply with the requirement of paragraph (1) of this 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 responsibility to warn passengers of 

the way to properly activate oxygen generator. 

(3) Within 7 months or 100 Flight Hours after the effective date of this AD, 

whichever occurs first, replace the existing oxygen generator release pin 

with an open pin P/N T700A351004410000, in accordance with the 

accomplishment instructions of SB No.70-168-35 initial issue. 

(4) Upon replacement of the existing oxygen generator release pin with an 

open pin P/N T700A351004410000, in accordance with the 

accomplishment instructions of SB No.70-168-35, remove 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 install in an aeroplane any 

oxygen generator release pin P/N T700A3510038100.
