Diamond Aircraft DA 62

The airframe is composite: carbon fibre or glass fibre set in resin, moulded in large pieces with few joints, which gives smooth shapes but needs different inspection and repair methods from metal. The design is held under 2 type certificates. The FAA has issued 2 airworthiness directives (orders that owners must comply with) that name this model, most of them about airframe structure. Operators and repair shops have filed 2 failure reports with the FAA since 2026, 2 of them in the last ten years: about 1.1 a year for every 100 aircraft on the register; the system most often named is electrical power. 7 approved modifications exist for it, the most by Diamond Aircraft Industries GMBH.

Sources: the FAA's type certificate data sheets, airworthiness directives, supplemental type certificates, special conditions and special airworthiness information bulletins (Dynamic Regulatory System), and the FAA's service difficulty reports. A failure report is what an operator or repair station chose to file; the counts show reporting as much as reliability, and larger and commercial fleets report more. How the systems are grouped.
