POKE WITH ED MART IN, LARRY BOHANNON AND KELLY JOHNSON

ABOUT THE PROBLEM OF THE INVERTED SCREWS IN THE PRIMARY FLIGHT

CONTROL MIXER UNIT. APPARENTLY BOHANNON AND KELLY READ THE RIOT

ACT TO MARTIN, BOEHME AND COMPANY CONCERNING THE BASIC DESIGN

IX IS UNDERWAY WHICH CONSISTS PRIMARILYOCKWIRED

RETAINER RING TO PREVENT ALL SCREWS IN THIS ASSEMBLY FROM FALLING

OUT SHOULD THEY LOOSEN. DESIGN SUCH AS THIS IS IN DIRECT VIOLATION

OF THE AIR FORCE HANDBOOK AND FAA REGULATIONS, BUT APPARENTLY

THESE REQUIREMENTS ARE BYPASSED WHENEVER THEY CONFLICT WITH LAC

DESIGN. THEY ALSO USE LOCKNUTS IN PRIMARY FLIGHT CONTROLS RATHER

THAN LOCK WIRE OR COTTER KEYS. ERSONALLY WOULD NEVER APPROVE

SUCH INSTALLATIONS.

OWEVER, LAC FEELS THE PROBLEM IS SERIOUS ENOUGH (WE

ALMOST LOST AN AIRCRAFT) THAT THE ENTIRE MECHANICAL, ELECTRICAL,

AND HYDRAULIC SYSTEMS ARE BEING REVIEWED TO DETERMINE IF OTHER

POTENTIAL HAZARDS OCCUR AND TO CORRECT SAME.

END OF MESSAGE
