Reason for the AD
The directive was issued following the discovery of a manufacturing defect in turbocharger hoses that could lead to failure and significant loss of engine power. This condition poses a hazardous situation during flight, necessitating immediate action.
Required Actions and Compliance Times
For Group 1 aeroplanes, the affected turbocharger hoses must be replaced within 20 flight hours or 30 days after the effective date of the AD, whichever comes first. Group 2 aeroplanes must not install affected parts from the effective date of this AD.
Definitions
The AD defines affected parts as turbocharger hoses with specific part numbers and batch numbers, while serviceable parts are those that are not affected. It categorizes aeroplanes into Group 1 (with affected parts) and Group 2 (without affected parts).
References
The AD references specific Service Bulletins issued by Continental Aerospace Technologies that provide detailed instructions for identifying and replacing the affected turbocharger hoses.
Safety notes
- Failure to comply with this AD could result in significant loss of engine power, leading to hazardous conditions during flight.

Confirm revision status through the EASA-Internet/Intranet. An agency of the European Union Page 2 of 3 Definitions: For the purpose of this AD, the following definitions apply: The applicable SB: Continental Aerospace Technologies Service Bulletin (SB) SB CG 601-1014 P1 (for Cessna (F)172, EASA STC 10014287) or SB CG 651-1009 P1 (for Piper PA-28, EASA STC 10014364), as applicable. Affected part: Turbocharger hoses, having Part Number (P/N) TAE EPA 40-7520-H0131 01, manufactured by ‘BOOST products’ and having batch number ‘3101-001’. Serviceable part: Any turbocharger hose, eligible for installation, which is not an affected part. Groups: Group 1 aeroplanes are those that have an affected part installed on the engine. Group 2 aeroplanes are those that do not have an affected part installed on the engine. Reason: During a pre-flight check, a defect turbocharger hose was found on an aeroplane. Investigation determined that a manufacturing defect exists on turbocharger hoses of a certain batch from one manufacturer. These turbocharger hoses are not pressure stable and it was determined that they could fail completely. This condition, if not corrected, could lead to significant loss of engine power which, in certain phases of flight and under certain operational conditions, could result in a hazardous condition. To address this potential unsafe condition, Continental Aerospace Technologies issued the applicable SB (original issue and Revision 01) to provide instructions for turbocharger hose identification and replacement. For the reason described above, this AD requires removal of affected parts from engines installed on Cessna (F)172 and Piper PA-28 aeroplanes, and prohibits (re-)installation. This AD is republished to correct and clarify the list of aeroplane models which may have a TAE 125-02-99 or TAE 125-02-114 engine installed through EASA STC 10014287 or EASA STC 10014364, as applicable. This AD also adds SB CG 601-1014 P1 Revision 02 (correcting the ‘Type affected’) to the reference publications. Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previously: Replacement: (1) For Group 1 aeroplanes: Within 20 flight hours or 30 days, whichever occurs first after the effective date of this AD, replace the affected part with a serviceable part in accordance with the instructions of the applicable SB. Parts Installation: (2) Do not install an affected part on any engine, or an engine with an affected part on any aeroplane, as required by paragraph (2.1) or (2.2) of this AD, as applicable.
