echanics, on Pages 25-26 of PS 733 (Dec 13), we told you how to remove a
faulty diode assembly for the reverse work light on the standard aircraft towing
system (SATS), NSN 1740-01-575-5662. That’s because a failed diode could cause
uncontrolled movement of the SATS.
By now, all the bad diodes should have been removed, based on safety action
message AGSE-13-ASAM-01.
For a more permanent ±x to the problem, PM AGSE and the original equipment
manufacturer (OEM) came up with a solution that uses a reverse light relay assembly
to stop uncontrolled movement. The details are in aviation maintenance action
message AGSE-13-AMAM-01, so check it out. The new procedures will also appear
in an upcoming change to TM 1-1740-221-13&P. If you don’t have the message yet,
here are the details.
