| Background: | Since the issue of EASA AD 2007-0190 (AD/F406/17), several instances of leakage of the new part number 4063700-1 blowdown bottle have been reported. Investigation revealed the cause of leakage was due to a manufacturing process which has now been resolved; therefore AD/F406/17 remains valid. Unless corrected, loss of blowdown bottle pressure could result in the inability to extend the landing gear in an emergency situation. |
