For what it's worth, the FAA specifies 9g "emergency landing loads" for equipment design. Basically, if it's a crash a human might survive, then the equipment and the safety features have to remain intact (or contained) following a crash. Nothing has to work after a crash, except for the crash-survivable flight data recorder ("black box") and emergence locator transmitter.
For what it's worth, I think it would be cool to frame a drop ship crash in terms of...
When your drop ship goes down, roll +lucky.
*Easy down - on a 10+, crew and passengers take 4 dice incidental fire. Sensitive equipment is on the blink; but, recoverable.
*Rough landing - on a 7-9, crew and passengers take 4 dice direct fire. Sensitive equipment is inop; but, most systems are salvageable to at least some degree.
*Hard crash - on a miss, crew and passengers take 4 dice concentrated fire. Equipment is inop; but, parts might be scavenged.
