The
Commission for the Investigation of Aviation Accidents, The
Commission for the Investigation of Aviation Accidents also found other contributing factors that were the following: • An incorrect and maybe missing data about the measurements of mechanical components of the shimmy damper kinematic system that are probably not present inside the Aircraft Maintenance Manuals (AMM) that are handed over to
Peruvian Airlines, the presence of this data's would have permitted to take timely detection and replacements of components that are overcome their tolerance limits; • The
Boeing service letter named Main Landing Gear (MLG) Lower Torsion Link Fractures does not required any mandatory action to prevent problems but only recommends maintenance actions to prevent fractures in the mechanical components of the shimmy damper system; • The Boeing service letter named Main Landing Gear Lower Torsion Link Fractures is too complicated to interpret and possibly confusing about which one Aircraft Maintenance Manuals actions are to take in consideration and in which ambit. ==Notes==
