AD NUMBER: 2004-09-05
MANUFACTURER: Cessna
SUBJECT: Airworthiness Directive 2004-09-05
SUMMARY: This amendment adopts a new airworthiness
directive (AD); applicable to certain Cessna Model 500, 501, 550,
and 551 airplanes; that requires a one-time inspection of the brake
stator disks to determine to what change level they have been
modified (if any), and related investigative and corrective actions
if necessary. This AD also requires that the existing markings on
the piston housing of certain brake assemblies be eliminated. The
actions specified by this AD are intended to prevent wheel lockups
that may be caused by cracked or broken brake stator disks becoming
jammed in the brake assembly and preventing rotation. Such
