Introduction
This Special Airworthiness Information Bulletin alerts you, repair
stations, mechanics holding Inspection Authorization (IA) and Flight
Standard District Office (FSDO) Principal Maintenance Inspectors (PMI)
and/or Principal Avionics Inspectors (PAI) of service difficulties and
safety issues associated with Flight Data Recorders on Empresa
Brasileira de Aeronautica S. A (Embraer) Model EMB-135 and EMB-145
airplanes.
Background
Examination of the recorded data from flight data recorders
installed in the Embraer EMB-135 and EMB-145 aircraft has revealed that
some of the data is not being updated at a rate sufficient to meet DFDR
sampling rate requirements of, 14 Code of Federal Regulations Part
121.344, Appendix M. Lack of reliable data from the flight data
recorder could hamper discovery of the cause of an accident or an
incident, and hinder the FAA in developing and mandating actions to
prevent subsequent accidents or incidents.
Recommendation
The FAA recommends all U.S. operators of Embraer 135 and 145 aircraft
series airplanes incorporate Embraer Service Bulletin 145-31-0042,
Revision 2 dated June 23, 2004, or Revision 3 dated December 17, 2004
or a later revision, to bring the required flight data recording into
compliance with 14 Code of Federal Regulations Part 121.344, Appendix M.
