Amdt 1
Flap 20 Degree Limit Stop 3/88
Applicability: SF 340A with S/Nos. 004 to 138 not incorporating Modification No 1462 and 1784. Requirement: Action in accordance with S.B. SF 340-27-036.
Note: Swedish BCA AD 1-015 Rev B refers.
Compliance: Prior to further flight after 5 May 1986.
Background: It has been established that an insufficient margin of flow separation exists on the right hand stabilizer during certain icing conditions that need not be severe.
Additionally, it has been found that the flight manual restriction was insufficient in that pilots were having difficulty in determining if an ice degraded condition existed. Amendment 1 provides for the restoration of full flap travel in modified aircraft and extends aircraft effectivity.
