After a 13 year restoration, the
world's only airworthy 247 was returned to the skies. The
airplane has flown routinely for years and is maintained by qualified
Museum volunteers and flown by qualified pilots. The airplane is
currently laid up due to finding cracks in the main landing gear.
Entirely new - improved - landing gears have been designed
(after more than 70 years!) and are currently being manufactured
from scratch.
FAA Annual Inspections are performed by A&P mechanics, including such things as gear swings.
