Stabilizer/stinger
Locate the stinger and tail rotor guard
Ensure the stinger is securely mounted and all hardware is tight/secure
Ensure if there is a torque stripe on the bottom of the stinger, that it is undamaged
Ensure the tail rotor guard is securely mounted and all hardware is tight/secure
Ensure the torque stripes are in a continuous line and not broken
Check height of stinger; stinger height within 34 inches of the ground requires rear crosstube replacement
