What was found
(CAN) BOTH THE LT AND RT LOWER VISOR ASSEMBLIES WERE FOUND DAMAGED FROM CRACKING AT THE AFT TOP END. THIS MAY HAVE BEEN DUE TO FLUTTER AT THE AFT END OF THE FAIRING DURING FLIGHT. SINCE IT IS ATTACHED TO THE MOVABLE HORIZONTAL STABILIZER, THERE IS NO FASTENERS AT THAT AFT END OF THE FAIRING. THERE WERE NO VIBRATIONS OR DEFECTS OF THAT THAT NATURE REPORTED ON THIS AIRCRAFT BEFORE IT CAME IN FOR A HEAVY CHECK DURING WHICH TIME THIS DAMAGED FAIRINGS WERE FOUND. HOWEVER THIS DAMAGE IS OFTEN NOTED ON OTHER AIRCRAFT AS WELL AND MAY OR MAY NOT HAVE CAUSED AIRFRAME VIBRATION OR INTERFERENCE WITH THE MOVING HORIZONTAL STABILIZER. (TC NR 20060919004)
