NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE APPLICABLE TO GROB G102, G103, AND G104 SERIES SAILPLANES AND G109 SERIES MOTORGLIDERS REQUIRING WITHIN THE NEXT 10 HOURS TIME-IN-SERVICE: (1) AN INSPECTION OF THE WING SPOILERS IN THEIR FULLY DEPLOYED POSITION TO ENSURE THAT ADEQUATE RIGGING CLEARANCE (OVERLAP) EXISTS IN THE RECESSED SPOILER CAP AREA, AND (2) AN INSPECTION OF THE WING SPOILER STOP BLOCK FOR EXCESSIVE WEAR OR DAMAGE. STOP BLOCKS EVIDENCING THESE CONDITIONS SHOULD BE REMOVED AND REPLACED BEFORE FURTHER FLIGHT. (URGENT)
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an urgent airworthiness directive for Grob G102, G103, G104 series sailplanes and G109 series motorgliders. Within the next 10 hours of service, operators must inspect the wing spoilers in the fully deployed position to verify adequate rigging clearance in the recessed spoiler cap area, and inspect the wing spoiler stop block for excessive wear or damage, replacing any affected blocks before further flight.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
