Plain English Summary

2/10 complexity

This Airworthiness Directive requires owners/operators of Aerospatiale (Socata) TB9 and TB10 aeroplanes (serials 1–944) fitted with a lower-cowling carburettor air supply to carry out the inspections/repairs specified in DGAC AD 90‑240(A) (per the published Requirement Document) by the revised effective date (31 March 1991). It responds to a risk that overtightened carburettor hose clamps can damage the NACA fitting, allowing the intake hose to loosen and possibly restrict engine operation; costs fall to operators.
