PRODUCT: All HPH s. r.o. Models 304C, 304CZ, and 304CZ-17 sailplanes. SUBJECT: Airworthiness Directive 2012-16-03 ACTION: Final Rule
SUMMARY: 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 the lack of a drain hole in the elevator control rod, which may allow water to accumulate in the control rod and lead to possible corrosion. This condition could cause the elevator control rod to fail, which could result in loss of control of the sailplane.
