Plain English Summary

3/10 complexity

The Civil Aviation Safety Authority has cancelled AD/LANCAIR/3, which previously limited the flight envelope of Lancair series kit aeroplanes. That directive was issued after kit‑manufacturer quality‑control deficiencies made composite material properties suspect.

Following investigation, the Authority found the material meets current certification standards and lifted the operational restriction. Remaining concerns about material ageing will be addressed separately and may prompt future action.

AD/LANCAIR/3 Fibre Composite Primary Structure 2/98

CANCELLED.

Background: The Authority became aware of deficiencies in the kit manufacturer's system of quality control. As a result, the material properties used in the LANCAIR kits became suspect. AD/LANCAIR/3 was raised to restrict the flight envelope of the aircraft pending an investigation into the effect of these changes. The results of the investigation showed that the material is presently suitable for the current aircraft certification standard. Concerns with potential aging properties of the material will be separately addressed.
