What to do
Operators of Grob G 115E and G 115EG aeroplanes must inspect all flight control surface attachment bolts before the next flight after 3 March 2021. If any discrepancies are found during inspection, corrective actions must be completed before further flight. Inspection results, including cases with no findings, must be reported to Grob Aircraft within 30 days of inspection.
Summary
EASA Airworthiness Directive 2021-0057-E is an emergency directive addressing the inspection of control surface hinge bracket attachment bolts on Grob Aircraft SE G 115E and G 115EG aeroplanes. It mandates a one-time inspection to detect potential structural penetration by attachment bolts that could lead to control surface failure. The directive applies to all serial numbers of the affected aircraft models.
What changed
This new directive introduces a mandatory inspection requirement for all flight control surface attachment bolts on Grob G 115E and G 115EG aeroplanes. It requires operators to inspect the bolts before the next flight after the effective date and to perform corrective actions if discrepancies are found. Additionally, inspection results must be reported to Grob Aircraft within 30 days.
Why it matters
This directive is critical for aviation professionals because undetected penetration of attachment bolts can compromise the structural integrity of control surfaces, risking loss of aircraft control. Operators and maintenance organizations must ensure compliance to maintain airworthiness and prevent potential in-flight failures. The directive also emphasizes timely reporting to support ongoing safety assessments.
