From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.19) On July 17, 2001, about 1413 eastern daylight time, a Mcdonnell Douglas MD-83, N9406W, operated by trans world airlines inc., operating as a title 14 CFR part 121 scheduled flight had an in-flight separation of internal engine parts while on initial climb out from Miami International Airport Miami, Florida. Visual meteorological conditions prevailed. An IFR flight plan was filed. The airplane was not damaged. The two airline transport-rated pilots, 3 flight attendants, and 94 passengers reported no injuries. One person on the ground reported minor burns, and 9 vehicles were damaged. The flight was originating at the time and was en route to john f. kennedy international airport, new york city, new york. According to the captain, a maximum thrust takeoff was initiated. At an altitude of about 600 to 800 feet "a loud boom was heard, accompanied by a strong shake of the airplane." The first officer (f/o) noted that the "... Epr (engine/exhaust pressure ratio) had gone to zero and the EGT (exhaust gas temperature) was at 80C." The flight crew declared an emergency, and because of storms north of the airport they had requested a left turn after departure. At the time of the engi NE failure the airplane was heading 210 degrees. The left turn was continued with the intent to land on runway 30. The APU (auxillary power unit) was left running. The f/o had initiated the emergency procedures for the failed engine, and "... A loud chattering began at this time along with the loss of most of the captain's instruments." The left engine generator was turned off, "... The chattering stopped, and the APU picked up the left elect {SIC}." The captain retarded the throttle and noticed "an accompanied yaw." He then added a "small throttle movement," and noticed a yaw to the "right...the engine was still producing thrust." The airplane landed without further incident, taxied to the gate, and parked. Everyone onboard exited the airplane at the gate. Many pieces of debris fell into a parking lot of a furniture store about 1/4 of a mile south of runway 27L. In addition to deris falling into the parking lot pieces of debris were also found on the roof of the furniture store and an adjacent building about 300 yards to the south. About 9 cars received damage in the form of broken windshields, dents and dings. The majority of the pieces were confirmed to be turbine blades. In a ddition, 14 pieces of turbine blade shroud were retrieved and all the pieces of debris will accompany the left engine (number 1) to twa's facility in Kansas city, Kansas, where an external examination of the number 1 engine (p&w model JT8-217) will be conducted. (-23)on t/o at approx. 800' #1 eng compressor stalled. No fire warning contined to operate engine. Returned to mia. Shutdown engine when a/c was on runway. Inspection revealed turbine damage. No airframe damage noted. Engine changed at mia by twa personnel.
