AMSEL-RD-NV-SE-EWD (SFAE-AV-AEC/25 Apr 1994) (70-lr) lst End Mr. R. Paolella and Ms. P. Lumjx44697 and x43211 SUBJECT: Failure Analysis on Crash Damaged Electronic Equipment Director, Survivability Equipment Division FOR PM-AEC, ATTN: SFAE-AV-AEC, 4300 Goodfellow Blvd. St. Louis, MO .63120-1798 1. A damaged ~144 jammer was handcarried from PM-AEC St. Louis, MO to SurviVaEllity Equipment Division, Fort Monmouoh, NJ by Mr. Q. Rodriguez via OA Form 4137 to perform a failure analysis of the damaged equipment with certification by the partic.ipants. 2. Prior to performing any failure analysis photographs of the damaged "ALQ-144~' iwas taken. As shown in the photos, the so called damaged system is not a damaged system but a destroyed subsupport assembly, which is part of the transmitter, Tl360A/ALQ-144A;, a major component of the AN/ALQ-l44A. The analysis was performed and the following damage assessment is being provided: a. The subassembly and the remaining attached parts, motors, encoder discs, start relay EMI filter, harnesses, lower portions of source, and modulators were burnt to the extent that a failure analysis could not be made other than what was observed. b. The subassembly was definitely part of AN/ALQ-144A. The lower portions of the infrared source, the low and high speed modulators and by the part numbers verified the A configuration, verified by the photos. c. There were no particles, pieces and/or parts of the low speed modulator lens and of the outer window assembly which in essence is glass (silicon), was to be found with the remanence submitted. d. There was no card cage which housed the 4 major circuit card assemblies (cca) (which included reprogrammable cca, A9) and the Estimated Time Indicator, even though the motors, filter, etc. were still intact. The cage screws were sheared and only the small bracket was remaining which seemed odd. e. There was no bottom cover and any parts there of for analysis. No attachment screws inspection doors nameplates, etc. f.
There was no operator control unit.
g. The subassembly was disassembled and photos were taken of the components. CERTIFICATE
