During a hard landing, which MSP code requires the jet to be lifted onto jacks?

In the context of a hard landing, MSP code 904 specifically denotes that the aircraft must be lifted onto jacks for a thorough inspection and assessment. The necessity to lift the jet onto jacks arises from the need to carefully examine the landing gear, fuselage, and other vital components that could be affected during a hard landing.

This process is crucial because a hard landing can lead to unseen structural damage or issues with the landing gear's alignment and functionality. By using the jacks, maintenance personnel can examine the aircraft from a stable position, allowing them to check for any deformities or malfunctions that might not be evident when the aircraft is on the ground.

The other codes in the MSP system relate to different procedural requirements for inspections or repairs following various incidents, but they do not specifically indicate the requirement to lift the aircraft for detailed examination as code 904 does. This targeted inspection is vital for ensuring the airworthiness of the aircraft after experiencing a potentially damaging landing scenario.
