Airworthiness Directives; Socata-Groupe Aerospatiale Models MS 892A-150, MS 892E-150, MS 893A, MS 893E, MS 894A, MS 894E, Rallye 150T, and Rallye 150ST Airplanes
This amendment supersedes Airworthiness Directive (AD) 2002- 05-04, which applies to certain Socata--Groupe Aerospatiale (Socata) Models MS 892A-150, MS 892E-150, MS 893A, MS 893E, MS 894A, MS 894E, Rallye 150T, and Rallye 150ST airplanes. AD 2002-05-04 requires you to repetitively inspect any engine mount assembly that is not part number 892-51-0-035-0 (or FAA-approved equivalent part number) for cracks; repair cracks that do not exceed a certain length; and replace the engine mount when the cracks exceed a certain length and cracks are found on an engine mount that already has been repaired twice. This AD is the result of the French airworthiness authority's determination that airplanes equipped with an engine mount assembly part number 892- 51-0-035-0 also display the unsafe condition. This AD retains the repetitive inspection and repair requirements of AD 2002-05-04, changes the applicability section, removes the terminating action, and requires replacement of all part number 892-51-0-035-0 engine mount assemblies. The actions specified by this AD are intended to prevent failure of the engine mount assembly. Such failure could result in loss of control of the airplane.
