AD - Model 500, 501, 550, and 551 Airplanes

2004-09-05 CESSNA AIRPLANE COMPANY: Amendment 39-13594. Docket 2000-NM-65-AD.

Airworthiness Directives; Cessna Model 500, 501, 550, and 551 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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 jamming of the brake assembly may result in reduced directional control or braking performance during landing. This action is intended to address the identified unsafe condition.

DATES: Effective June 2, 2004.

    Applicability: Model 500 and 501 airplanes, serial numbers 0001 through 0689 inclusive, and Model 550 and 551 airplanes, serial numbers 0002 through 0733 inclusive; certificated in any category; equipped with BFGoodrich brake assembly part number (P/N) 2-1528-6 or 2-1530-4.

    Compliance: Required as indicated, unless accomplished previously.

    To prevent jamming of the wheel/tire assembly, which could result in a loss of directional control or braking performance upon landing……
