EASA AD 2022-0101-E
Wings — Outer Wing Connection — Inspection
Summary
EASA Airworthiness Directive 2022-0101-E is an emergency directive addressing a structural issue in Stemme AG S12 powered sailplanes, specifically affecting outer wing connections with part numbers 012403 (right-hand side) and 012402 (left-hand side). The directive mandates inspection of these outer wing connections due to a production deviation causing incorrect positioning of glass-fibre reinforced plastic blocks in the outer wing spar. This AD applies to Stemme S12 sailplanes with serial numbers 12-002 to 12-042 inclusive and 12-044.
What Changed
This new emergency airworthiness directive introduces a one-time inspection requirement for the outer wing connections of affected Stemme S12 sailplanes to detect any deviations in the positioning of GFRP blocks. If discrepancies are found, corrective actions must be taken before further flight. The directive also references Stemme Service Bulletin P062-980060 for inspection and corrective procedures.
Why It Matters
This directive is critical for maintaining the structural integrity of the wing connection on affected sailplanes, preventing potential wing rupture and loss of control. Operators, maintenance organizations, and compliance teams must ensure timely inspections and repairs to avoid unsafe flight conditions. Compliance with this AD ensures continued airworthiness and regulatory adherence for the affected aircraft.
What To Do
Before the next flight after 6 June 2022, operators must inspect each affected outer wing part following the instructions in Stemme Service Bulletin P062-980060. If any discrepancies are found during inspection, operators must contact Stemme for approved corrective actions and complete those repairs before further flight.
