63-09-01 BENDIX: Amendment 560 Part 507 Federal Register April 27, 1963. Applies to All Aircraft Equipped With Bendix (Eclipse-Pioneer) Type 9054 Fuel Flow Transmitters or With Beech P/N 414-180824 Fuel Flow Transmitters or Garwin P/N 8007 Fuel Flow Transmitter Which Incorporate the Bendix Type 9054 Fuel Flow Transmitter.
Compliance required for Bendix (Eclipse-Pioneer) Type 9054 transmitters within 150 hours' time in service after the effective date of this AD unless already accomplished and for Beech P/N 414-180824 and Garwin P/N 8007 transmitters within 150 hours' time in service after the effective date of this amendment.
Cracks have occurred in the magnet bore of the transmitter motor mounting frame releasing hazardous quantities of fuel into the power-plant compartment. Failure is attributed to improper chamfer and corner radius of the magnet bore and, also, the thickness of the magnet bore back wall. To prevent bore failures, accomplish one of the following:(a) Replace the transmitter with a transmitter complying with Bendix (Pioneer-Central) Service Bulletin No. FF-19 or Bendix (Eclipse-Pioneer) Service Bulletin No. 245; or
(b) Verify that the transmitter has been inspected and found to comply with Bendix (Eclipse-Pioneer) Service Bulletin No. 245; or
(c) Disassemble the transmitters, accomplish inspections and install if necessary, replacement motor mounting frame Bendix P/N PD-50297-1 as outlined in Bendix Service Bulletin No. FF-19.
Transmitters complying with (a), (b) or (c) shall be marked with a 1/4 inch external white band on the Autosyn end of the frame as described in Service Bulletin No. FF-19. Installed transmitters reworked prior to the effective date of this AD are to be marked at the next transmitter overhaul or removal whichever occurs first.
NOTE: Bendix 9054 and 9100 transmitters with the Bendix identification removed are used to make up Beech P/N 414-180824 and Garwin P/N 8007 transmitters. The affected Beech and Garwin transmitters with the 9054 units have a 2.205 inch diameter autosyn housing, while the unaffected units with the 9100 part have a 1.75 inch diameter housing.
