Summary Uncontained turbine failure Site Escambia County, Florida, near Pensacola Similar 1972 Chicago–O'Hare runway c, Delta Air Lines Flight 723, Delta Air Lines Flight 1141, Delta Air Lines Flight 9570, ADC Airlines Flight 86 | ||
Delta Air Lines Flight 1288 was a regularly scheduled flight from Pensacola, Florida to Atlanta, Georgia on a McDonnell Douglas MD-88 equipped with Pratt & Whitney JT8D-219 turbofan engines. During the flight's takeoff roll from runway 17 at Pensacola on July 6, 1996, the aircraft experienced an uncontained, catastrophic turbine engine failure that caused debris from the front compressor hub of the number one left engine to penetrate the left aft fuselage. The impact left two passengers dead and two severely injured; the two dead were a mother and son. The pilot aborted takeoff and the airplane stopped on the runway. Three other passengers sustained minor injuries during the emergency evacuation. Most of the passengers were traveling on vacation.

Pre-flight inspection
During the pre-flight inspection, the first officer noted a few drops of oil coming from the "bullet" or tip of the number one (left) engine, although it was said to be "not that serious". The first officer also noticed a couple of missing rivets on the left wing. The pilot told NTSB investigators that both problems were observed as non-threatening and that the aircraft was airworthy; therefore, maintenance was not informed.
Takeoff and incident
At 2:23 pm CDT, Delta Flight 1288 was cleared for takeoff on Runway 17. As the first officer was advancing the throttles and reaching an airspeed of 40 knots, the cockpit lost lighting and instrumentation. The rear cabin passengers and flight crew heard a very loud bang and experienced a blast-like sensation. The pilot then ended takeoff by bringing the throttle to idle and engaging the brake, which brought the aircraft to an eventual stop without use of reversers or spoilers.
Once the aircraft stopped, the first officer attempted to contact the tower; however, he was unable due to the cockpit's lack of power. The flight crew then activated emergency power, contacted Pensacola tower, and declared an emergency. The cockpit's jump-seat passenger, an off-duty Delta Boeing 767 pilot, went to inspect the rear of the aircraft. When the first officer saw the over-wing exits open and about half of the passengers missing along with hearing engine noise, he returned to the cockpit and advised the captain to kill the engines. At 2:27 pm CDT the pilot requested emergency medical assistance due to the jump-seat passenger's report of a large hole in the fuselage, engine debris throughout the cabin, and injured passengers. He then reported there was no evidence of smoke or fire in the cabin, and that the rear cabin door had been opened and the emergency slide was inflated. The flight attendant who initiated the evacuation through that door told the NTSB that she saw fire on the left engine and therefore abandoned evacuation through that door and directed passengers forward. She reported that there were many injuries and possibly two dead, and that therefore she began to evacuate the plane until she was stopped by the first officer. Due to the damage to and danger at the rear of the aircraft, the air stairs built into the MD-88 were found unsuitable to use. The captain then requested portable air stairs to deplane passengers, which arrived 25 minutes later.
Injuries and deaths
Anita L. Saxton, 39, of Scottville, Michigan and her 12-year-old son Nolan Saxton sustained fatal injuries. Ms. Saxton's son, 15-year-old Derek Saxton, and 9-year-old daughter Spencer Saxton sustained non-fatal injuries. Five total passengers were injured. One passenger was listed in serious condition with a fractured leg.
NTSB investigation
After a total investigation, the NTSB determined the most probable cause of the accident was a fracture in the left engine's front compressor fan hub, which resulted from failure of the airline's fluorescent penetrant inspection process to detect a potentially dangerous crack in the fan which originated from the engine's initial manufacture. The NTSB also attributed the accident to the failure of Delta's maintenance team to discover the problem.
Aftermath
As of August 2016, the FAA reports the aircraft involved in the incident is still in service with Delta and registered as N927DA. Delta currently uses the MD-88/MD-90, Airbus A319/A320, and Boeing 757-200 aircraft on its Pensacola-Atlanta route. As of May 2016, "Flight DL1288" is used on a New York LaGuardia-Fort Lauderdale route.
