## EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0075R1

Date: 24 April 2014

Note: This Airworthiness Directive (AD) is issued b y EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Communit y, its Member States and of the European third countries that participate in the ac tivities of EASA under Article 66 of that Regulation.
This AD is issued in accordance with EU 748/2012, P art 21.A.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 accordan ce with the requirements of that AD, unless otherwi se 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, A rticle 14(4) exemption].

Revision: This AD revises EASA AD 2014-0075 dated 2 5 March 2014.



### ATA 28 Fuel – Fuel Probes – Inspection / Replacemen t

Manufacturer(s): ATR-GIE Avions de Transport Région al (formerly Aerospatiale – Aeritalia, Aerospatiale – Alenia, Aerospatiale ATR – ALENIA, E ADS ATR – Alenia).
Applicability: a) ATR 42 and ATR 72 aeroplanes, all certified models, all Manufacturer Serial Numbers (MSN) qualified for Extended range Twin OPerationS (ETOPS) in accordance with ATR Mod. 04711, or b) ATR 42 aeroplanes, all certified models, all MSN , except aeroplanes which
are: - modified in accordance with ATR Mod 04650, or
- retrofitted in accordance with ATR Service Bullet in (SB) ATR42-28-0033 or SB ATR42-28-0034, as applicable to the aeroplane model, or c) ATR 72 aeroplanes, all certified models, all MSN , except aeroplanes which
are: - modified in accordance with ATR Mod 04686, or
- retrofitted in accordance with ATR SB ATR72-28-10 13, SB ATR72-28-1022 or SB ATR72-28-1023, as applicable to the aeroplane model.
Reason: A significant number of fuel probes install ed on ATR aeroplanes failed during production tests and several occurrences of fuel qu antity indication malfunctions were recently reported on in-service a eroplanes. The subsequent investigation, conducted on the fail ed parts, confirmed a lossEASA AD No.: 2014-0075R1

The investigatio n identified a batch of parts, suspected to be affected by this manufacturi ng defect. Some of these probes were delivered as spares, and operators may have installed these probes on their in-service aeroplanes. In case an affected fuel probe is installed on each wing of an aeroplane, being not equipped with an independent fuel low level mea surement system or an aeroplane operated in accordance with ETOPS rules, the defected fuel probes could indicate a higher fuel quantity value than th e real quantity of the on-board fuel. This condition, if not detected and corrected, coul d lead to an undetected fuel starvation and consequent dual engine in-flight fla me out. For the reasons described above, this AD requires t he identification and replacement of the affected fuel probes. This AD is revised to correct typographical errors.

Effective Date: Revision 1: 24 April 2014 Original issue: 08 April 2014
Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previous ly: (1) Within 5 000 flight hours or 24 months, whichev er occurs first after 08 April 2014 [the effective date of this AD at original iss ue], accomplish the following actions: (1.1) Identify the Part Number (P/N) and serial num ber (S/N) of the fuel probes installed on the aeroplane in accordance wit h the instructions of ATR Aircraft Maintenance Manual (AMM) Job Instru ction Card (JIC) 28-42-72 RAI 10000. A review of aeroplane maintenance records is accep table to make the identification as required by paragraph (1.1) o f this AD, provided those maintenance records can be relied upon for th at purpose, and the P/N and S/N of the fuel probes can be conclusiv ely identified from that review. (1.2) Following the identification required by para graph (1.1) of this AD, replace any fuel probe, having a P/N and S/N as lis ted in Table 1 of this AD, with a serviceable part in accordance with the instructions of ATR AMM JIC 28-42-72 RAI 10000.
Note: For the purpose of this AD, a serviceable fue l probe is a part which is either: - not listed in Table 1 of this AD, or - listed in Table 1 of this AD, but having control tag “C” marked on the part identification plate, as specified in Zodiac Aerosp ace Services Europe Service Bulletin (SB) 766983-28-002. (2) From 08 April 2014 [the effective date of this AD at original issue], installation of fuel probe with a P/N and S/N liste d in Table 1 of this AD on an aeroplane is allowed, only provided that the con trol tag “C” is marked on the fuel probe identification plate, as specified i n Zodiac Aerospace Services Europe SB 766983-28-002.EASA AD No.: 2014-0075R1
