AD NUMBER: 2004-09-03 MANUFACTURER: HPH s.r.o. SUBJECT: Airworthiness Directive 2004-09-03 SUMMARY: The FAA adopts a new airworthiness
directive (AD) for certain HPH s. r. o. (HPH) Models Glasflugel
304CZ, 304CZ-17, and 304C sailplanes. This AD requires you to
inspect to determine the airbrake handle attachment rivet material.
This AD also requires you to replace any non-steel rivet with a
steel rivet. This AD is the result of mandatory continuing
airworthiness information (MCAI) issued by the airworthiness
authority for the Czech Republic. We are issuing this AD to prevent
the airbrake handle from becoming loose, which could result in
failure of the airbrake control. This failure could lead to loss of
control of the sailplane.
