AD NUMBER: 2007-23-06
MANUFACTURER: CTRM Aviation Sdn. Bhd.
SUBJECT: Airworthiness Directive 2007-23-06
SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: An operator has reported severe exfoliation corrosion on Wing/Canard Flap Hinges, P/N 5731D01-16 (middle and outboard hinges) on his Eagle 150B. The corrosion has been detected during 100-hour inspection. The aircraft has accumulated more than 1000 flight hours. The corrosion is so severe that one of the Flap Hinges thickness has been reduced by 50%. The corrosion is not easily detected because the Flap Hinge is sandwiched between the Flap Hinge Support Bracket P/N 5731D01-01. The failure of the hinge bracket may result in disintegration of flap/canard wing thus leading to loss of control, with catastrophic consequences. We are issuing this AD to require actions to correct the unsafe condition on these products.
