Fairchild Aircraft, Inc. Models SA226 and SA227 Series Airplanes

This amendment supersedes Airworthiness Directive (AD) 2001- 20-14, which currently requires you to replace the brake shuttle valves with parts of improved design and install a shield over the hydraulic lines on certain Fairchild Aircraft SA226 and SA227 series airplanes. AD 2001-20-14 also requires you to replace the rubber fuel hose with a metal device for certain SA226 series airplanes. This AD is the result of FAA incorrectly referencing Model SA226--T(A) airplanes and inadvertently omitting certain serial numbers of Model SA227--AC airplanes from the applicability of AD 2001-20-14. This AD retains the actions of AD 2001-20-14, corrects the reference of Model SA226--T(A) airplanes and adds additional Model SA227--AC airplanes to the applicability section of the AD. The actions specified by this AD are intended to correct potential brake shuttle valve problems, which could cause the brake assembly to drag and overheat. Hydraulic or fuel line damage could then occur if the overheated brake assembly is retracted into the main wheel well with a consequent fire if the hydraulic or fuel lines ruptured.
