INTRODUCTION:
The purpose of this Special Airworthiness Informati on Bulletin is to advise operators of Fairchild Merlin/Metro SA226/SA227 model airplanes of the need to review the service bulletins listed on page 2.
BACKGROUND:
A review of Fairchild Merlin/Metro SA226/SA227 Model Service Bulletins was conducted as part of the Aging Commuter Airplane program. Particip ation in the review included the certification branch of the Federal Aviation Administration (F AA), Fairchild Engineering and Customer Service representatives, a representative of the Regional Ai rlines Association, and several operators. The purpose of this review was to evaluate each age-re lated service bulletin and determine if any further FAA action was necessary to ensure the level of safety desired for commuter operations.
The options considered by the group included: mandated compliance by initiation of an FAA Airworthiness Directive, various forms of notices, or no further action required. The group reached a consensus with a recommended action for each service bulletin. The FAA and Fairchild further reviewed these recommendations and FAA determined that several of the service bulletins should be re-confirmed for compliance because they contributed to the higher level of safety expected for commuter operations.
RECOMMENDATION:
It is recommended that all operators of Fa irchild Metro SA226 or SA227 airplanes review compliance of the service bulletins listed on page 2. If compliance has not previously been accomplished, it is recommended that compliance be accomplished as soon as possible. For exact model and serial number effectivity, refer to the service bulletin.
NOTE: This is not an all inclusive list of service bulletins applicable to these airplanes.
