MANUFACTURER: Diamond Aircraft Industries GmbH
Model DA 40 and DA 40 F Airplanes SUBJECT: Airworthiness Directive 2009-10-04
SUMMARY: We are adopting a new airworthiness
directive (AD) for the products listed above to supersede an
existing AD. This AD results from mandatory continuing
airworthiness information (MCAI) issued by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
A case was reported where the NLG leg of a DA 40 aircraft
failed in the area of the nose gear leg pivot axle. The affected
airplane was mostly operated on grass runways and used for training
operations. The investigation showed that the failure was due to a
fatigue crack that had developed in the pivot axle. Subsequent
material inspections determined that these cracks may also develop
on other aircraft, depending on the type of operation.
This condition, if not detected and corrected, could lead to
further cases of NLG failure, possibly causing damage to the
aircraft and injuries to occupants. To address and correct this
unsafe condition, ACG issued AD A-2005-005 to require repetitive
inspections of the NLG leg and, in case cracks are found,
replacement of the NLG leg with a serviceable unit. Since that AD
was issued, Diamond Aircraft Industries developed a redesigned NLG
leg which is not affected by the cracking phenomenon addressed by
AD A-2005-005.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
