Narrative:
The crew had to pull Ground Control Relay circuit breakers H20 and J20 after takeoff due to cabin pressurization problems. When on final approach to RWY 02R at 100 feet the cabin had depressurized completely, so the captain reset both circuit breakers. Suddenly the spoilers deployed, which gave the aircraft a high sink rate. The DC-9 struck the runway with full power on both engines and a nose-high attitude. The aircraft bounced back and the crew managed to climb away. After landing back on RWY31 major damage was discovered to the fuselage.
PROBABLE CAUSE: "The flightcrew's improper procedures and actions (failing to contact system operations/dispatch, failing to use all available aircraft and company manuals, and prematurely resetting the ground control relay circuit breakers) in response to an in-flight abnormality, which resulted in the inadvertent in-flight activation of the ground spoilers during the final approach to landing and the airplane's subsequent increased descent rate and excessively hard ground impact in the runway approach light area.
Contributing factors in the accident were ValuJet's failure to incorporate cold weather nosegear servicing procedures in its operations and maintenance manuals, the incomplete procedural guidance contained in the ValuJet quick reference handbook, and the flightcrew's inadequate knowledge and understanding of the
aircraft systems."
