EASA EMERGENCY AIRWORTHINESS DIRECTIVE

AD No.: 2012-0097-E

Date: 31 May 2012

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 :

BRP-Powertrain GmbH & Co. KG

Type/Model designation(s):

Rotax 912 series engines

TCDS Number: EASA.E.121

Foreign AD: Not applicable

Supersedure: This AD supersedes EASA Emergency AD 2012-0093-E dated 26 May 2012.

ATA 73

Engine Fuel and Control – Fuel Pump Pressure Side Hose –

Replacement

Manufacturer(s): BRP-Powertrain GmbH & Co. KG, BRP-Rotax GmbH & Co. KG; BombardierRotax GmbH & Co. KG; Bombardier-Rotax GmbH.

Applicability: Rotax 912 A1, 912 A2, 912 A3 and 912 A4 engines, all serial numbers (s/n).

Rotax 912 F2, 912 F3 and 912 F4 engines, all s/n.

Rotax 912 S2, 912 S3 and 912 S4 engines, all s/n.

These engines are known to be installed on, but not limited to, the following 

types of aeroplanes: 3-i Sky Arrow 650 TC, 650 TCN, 650 TCNS and 710 RG; 

Aeromot AMT-200 Super Ximango; Aircraft Philipp (formerly Alpla-Werke; 

Nitsche) AVO 68 series Samburo; Aquila AT01; Cessna 150 and A150 series 

and (Reims) F150 and FA150 series; Diamond (formerly HOAC) H 36 Dimona, 

HK 36 series Super Dimona, DV 20 Katana and DA20-A1 Katana; EvektorAerotechnik EV-97 VLA; Grob G 109; Issoire APM-20 Lionceau; Scheibe SF 

36R and SF 25C; Tecnam P 92-J, P 92-JS and P2002-JF; W.D. Aircraft D4 

Fascination.

Note: The installation of these engines was either done by the respective 

aeroplane manufacturer or through modification of the aeroplane by 

Supplemental Type Certificate. 

Reason: Reports from the field confirmed a non-compliance of pressure side fuel hoses

installed on certain P/N 893114 fuel pumps, which may have resulted in a latent 

defect on a limited number of engines. The affected fuel hoses may not be fuel 

resistant in accordance with the specification.

This condition, if not corrected, could lead to detachment of particles from the

fuel hose and irregularities in the carburettor function, possibly resulting in inflight engine shutdown and forced landing, damage to the aeroplane and injury 

to occupants.

To address this potential unsafe condition, EASA issued Emergency AD 2012-

0093-E to require the replacement of the pressure side fuel hose on certain fuel 

pumps, identified by P/N 893114. That AD also prohibited installation of an 

affected engine on an aeroplane, unless the fuel pump installation of that engine 

had been corrected as required by the AD.

Since that AD was issued, the relevant BRP-Powertrain Alert Service Bulletin 

(ASB) ASB-912-061 has been revised (R1) to correct the list of affected P/N 

893114 fuel pumps, identified by s/n. As some of these pumps (including 

potentially defective hoses) have been delivered as spares, they could also be 

installed on other engines than those specified by s/n in BRP-Powertrain ASB912-061R1.

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

Emergency AD 2012-0093-E, which is superseded, expands the Applicability to 

all Rotax 912 series engines and corrects Table 1 - Affected P/N 893114 fuel 

pumps. In addition, 2 aeroplane types have been removed from the Applicability 

of this AD: Aeromot AMT 300 Turbo Super Ximango and Stemme S10 VT have 

a Rotax 914 engine installed, not a Rotax 912.

Effective Date: 01 June 2012

Required Action(s) 

and Compliance

Time(s):

Required as indicated, unless accomplished previously: 

(1) Before next flight after the effective date of this AD, accomplish the 

following actions concurrently:

(1.1) Inspect the P/N 893114 fuel pump installed on the engine to identify 

the s/n of the pump. In lieu of this inspection, a review of engine 

installation- or maintenance records is acceptable to identify the s/n 

of the fuel pump, provided those records can be relied upon for that 

purpose, and the s/n of the fuel pump can be conclusively identified 

from that review. Engines that are known to have had an affected fuel 

pump installed, as delivered by BRP-Powertrain, are also identified 

by engine s/n in BRP-Powertrain Alert Service Bulletin (ASB) ASB912-061R1. 

Table 1 – Affected P/N 893114 fuel pumps, identified by s/n:

11.3117 through 11.3325 inclusive

11.4036 through 11.4335 inclusive

11.4516 through 11.4595 inclusive

12.0251 through 12.0270 inclusive

(1.2) If the s/n of the fuel pump, identified as required by paragraph (1.1) of 

this AD, is listed in Table 1 of this AD, replace the pressure side fuel 

hose in accordance with the instructions of Section 3) of BRPPowertrain ASB-912-061R1.

(2) From the effective date of this AD, do not install a P/N 893114 fuel pump, 

identified by s/n in Table 1 of this AD, on an engine, unless the pressure 

side fuel hose of that pump has been replaced as required by paragraph 

(1) of this AD.

(3) From the effective date of this AD, do not install a Rotax 912 engine on an 

aeroplane, unless that engine has been inspected and, depending on

findings, corrected as required by paragraph (1) of this AD.
