Certification of the Adam Aircraft Industries A500 all-composite piston twin has slipped again, and is now forecast for March, around nine months later than originally planned. The A500 is the first aircraft to be developed by Englewood, Colorado-based Adam Aircraft, which says "there is no one thing" that has caused the delay.

The third prototype A500, flown on 12 December, is the first conforming aircraft and will be used for certification flight testing. Initial certification will not include flight into known icing, says Adam. Work has begun on the fourth aircraft, the first for a customer, and Adam hopes to begin deliveries of the $895,000 A500 as soon after certification as possible.
