EASA AD No.: 2015-0184 

EASA AIRWORTHINESS DIRECTIVE 

AD No 015-0184 

n Date: 01 September 2015 

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

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 EU 74812012, Part 21A3B. In accordance with EU 1321/2014 Annex I, Part MA301, 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 [EU 1321/2014 Annex I, Part MA303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption]. 

Design Approval Holder's Name: Type/Model designation(s): 

BRITTEN-NORMAN AIRCRAFT Ltd BN2, BN2A, BN28 (Islander) and 

BN2A MKIII (Trislander) aeroplanes 

TCDS Numbers: EASA.A.388, United Kingdom (UK) BA6, and UK Airworthiness Approval Notes 

9405.1, 10101, 10918, 10992, 11105 and 11108. 

Foreign AD: Not applicable 

Supersedure: This AD supersedes EASA AD 2013-0263 dated 29 October 2013. 

ATA 76 Engine Controls - Engine Control Cables - Inspection I 

Replacement 

Manufacturer(s): Britten-Norman Aircraft Limited, formerly B-N Group Ltd, Britten-Norman Ltd, 

Fairey Britten-Norman Ltd, Britten-Norman (Bembridge) Ltd, Pilatus BrittenNorman Ltd and PADC. 

Applicability: BN2, BN2A and BN2B (piston engine) "Islander'' aeroplanes, all models, all 

serial numbers, and BN2A MARK Ill "Trislander" aeroplanes, all models, all 

serial numbers. 

Reason: Britten-Norman Aircraft Limited was made aware of two occurrences where a 

failure of engine control cable assemblies has caused engine control 

difficulties. In both reported cases, the cable sliding end assemblies were in 

poor condition and in both cases, an incorrect end-fitting was installed, which 

may have contributed to the failures. 

This condition, if not detected and corrected, could result in reduced engine 

control, possibly resulting in reduced control of the aeroplane. 

To address this potential unsafe condition, Britten-Norman Aircraft issued 

Service Bulletin (SB) 334 to provide inspection instructions, and EASA issued 

AD 2013-0215 to require a one-time inspection and functional test of the engine 

control cables and, depending on findings, replacement of the cables. 

Subsequently, as it was found that BN2 "Islander" aeroplanes were mistakenly 

omitted from the AD applicability, EASA issued AD 2013-0263, retaining the 

requirements of EASA AD 2013-0215, which was superseded, and extending 

the applicability to BN2 aeroplanes.

EASAAD No.: 2015-01 84 

Since EASA AD 2013-0263 was issued, it was found that certain parts, specific 

to BN2A "Trislander" aeroplanes only, were inadvertently not included in SB 

334 and, as a consequence, not required by AD 2013-0263 to be inspected. 

Prompted by these findings, Britten-Norman revised SB 334 (now at issue 2) to 

include the missing parts. 

For the reason described above, this AD retains the requirements of EASA 

AD 2013-0263, which is superseded, and adds inspection requirements for the 

additional parts. 

Effective Date: 15 September 2015 

Required Action(s) Required as indicated, unless accomplished previously: 

and Compliance 

Time(s): (1) Within 6 months after 30 September 2013 [the effective date of EASA AD 

2013-0215], inspect the engine control cable assemblies, Part Number 

(PIN) 137835, P/N 172449-1, P/N 17250 and P/N 172451, and check the 

control linkages for proper adjustment, in accordance with the instructions 

of Section 6 'ACTION' of Britten-Norman Aircraft Limited SB 334. 

(2) Within 3 months after the effective date of this AD, inspect the wingmounted engine mixture sliding end assemblies P/N NB-45-2883 and other 

sliding end assemblies P/N 80468, and check the control linkages for 

proper adjustment, in accordance with the instructions of Section 6 

'ACTION' of Britten-Norman Aircraft Limited SB 334 Issue 2. 

(3) If, during the inspection and check as required by paragraph (1) or (2) of 

this AD, as applicable, discrepancies are detected, as identified in BrittenNorman Aircraft SB 334, before next flight, replace the affected engine 

control cable assembly or sliding end assembly, as applicable, with a 

serviceable unit. 

(4) From the effective date of this AD, installation on an aeroplane of engine 

control cable assemblies having PIN 137835, PIN 172449-1, PIN 17250 or 

P/N 172451, or sliding end assemblies PIN NB-45-2883 or P/N 80468, is 

allowed, provided these are new, or have passed the inspection and check 

as required by paragraph (1) or (2) of this AD, as applicable.
