## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
