Pittsburgh-Intl

Following an uneventful flight from Pittsburgh-International Airport, the crew deliberately started the descent prematurely, causing the aircraft to approach below the minimum published altitude. While descending in marginal weather conditions, the twin engine airplane struck an ILS antenna and crashed few dozen yards short of runway 33 threshold. A pilot and four passengers were seriously injured while 12 other occupants were killed. The aircraft was destroyed. By reason of numerous violations, unsafe practices, policies, and coercing tactics, Air East has demonstrated that it does not possess the judgement, responsibility or compliance disposition required of a holder of an air taxi commercial operators certificate. Thus, the operator's AOC was revoked on March 7, 1974.

Shortly after a night takeoff from Pittsburgh-Intl Airport, the twin engine airplane encountered difficulties to gain height then stalled and crashed in flames by the airport. The aircraft was destroyed and both pilots were killed.

The crew started the approach to Akron-Canton Airport by night and marginal weather conditions. The approach speed was too high and the airplane was also too high and the glide so the crew landed 2,400 feet to far down the runway 01. After touchdown on a wet runway, the airplane was unable to stop within the remaining distance, overran and came to rest. All 26 occupants were evacuated, 15 of them were injured. The aircraft was damaged beyond repair.

The aircraft was performing a flight from Pittsburgh to Cincinnati with an intermediate stop in Parkersburg. Upon landing at Parkersburg Airport, West Virginia, the crew encountered technical problems with the right main gear. The captain increased engine power and decided to return to Pittsburgh-Greater Pittsburgh Airport for a safe landing. Upon touchdown on runway 28R, as the wheels were missing on the right main gear, the airplane deviated from the centerline to the right when the left main gear collapsed as well. The airplane came to rest and was damaged beyond repair while all 53 occupants escaped uninjured.

While approaching Pittsburgh-Greater Pittsburgh Airport by night, the crew failed to realize his altitude was too low when the airplane struck tree tops and crashed 3 miles short of runway. All seven occupants were seriously injured and the aircraft was destroyed.

Flight 128 was a scheduled domestic flight from Los Angeles International Airport, California, to Boston, Massachusetts, with intermediate stops at Cincinnati, Ohio and Pittsburgh, Pennsylvania. The departure from Los Angeles was delayed due to an equipment change but the aircraft was airworthy at the time of departure. The only carry- over discrepancy was an inoperative generator which had no bearing on this accident. The flight took off from Los Angeles at 1737 hours Eastern Standard Time. The descent into the Cincinnati area from cruising altitude was delayed due to conflicting traffic and was initiated closer to the destination than normal. It required the crew to conduct the descent with a higher than normal rate toward the initial approach fix. The crew discussed the technique they were going to use to increase the rate of descent, and evidence revealed that they were relaxed, unworried and operating within the established operating limits of the aircraft. As the flight reported leaving 15 500 ft remarks were made in the cockpit about the rapidity of the descent and the hope, apparently with reference to the underlying cloud conditions, that it would be a thin layer. The crew checked the anti-icing equipment and conversations after that time indicated that they were not aware of any discrepancies regarding that system. Control of the flight was normal until the flight was turned over to the approach controller who failed to provide the crew with the current altimeter setting of 30.07 in Hg instead of 30.06 previously given to the crew. However, shortly after the crew intercepted a transmission to another aircraft containing the current altimeter setting of 30.07 they set and cross-checked that setting on their altimeters. Throughout the descent, the co-pilot called out the appropriate warnings to the pilot-in-command as the aircraft approached assigned altitudes and apparently performed all of his assigned duties without prompting by the pilot-in-command. Crew coordination was very good during that portion of the flight. The weather conditions in the Cincinnati area were such that the crew should have established visual contact with the ground by the time they reached 3 000 to 4 000 ft. As the flight approached the final fix, approximately 7 minutes before the accident, the crew was given the latest reported weather which indicated that the ceiling was approximately 1 000 ft and the visibility was 13 miles in snow and haze. Approximately 1 minute later they were reminded that the ILS glide slope was out of service, as well as the middle marker beacon and the approach lights. The crew acknowledged receipt of this information and planned their approach to the proper minimum altitude of 1 290 ft AMSL, 400 ft above the ground, to allow for these outages. From this point in the approach to the outer marker, the aircraft altitudes and headings were in general agreement with altitudes reported by the crew and the headings they were instructed to fly. Operation of the aircraft was normal and the proper configuration was established for the approach to the outer marker in accordance with the company's operating instructions. The crew reported over the outer marker at 2056 hours and were cleared to land on runway 18 and advised that the wind was 090°/8 kt and the RVR more than 6 000 ft (see Fig. 22-1). The co-pilot reported to the pilot-in-command that they were past the marker and that there was no glide slope. The pilot-in-command acknowledged this and stated ". . . We gotta go down to, ah, four hundred, that would be, ah." At this point, the co-pilot supplied the information "twelve ninety" and the pilot-in-command repeated "twelve ninety." The flight had arrived at the outer marker with the landing gear down, the flaps set at 40' down at an altitude of approximately 2 340 it and at an airspeed of approximately 200 kt. (The prescribed minimum altitude over the outer marker beacon, 4 miles from the threshold, was 1 973 ft AMSL). After the aircraft passed the outer marker, a rate of descent of 1 800 ft/min was established at an airspeed of about 190 kt. The rate of descent was greater than that recommended by the company for an instrument approach and remained nearly constant until approximately 20 sec before the first recorded sound of impact. At that time the rate increased to approximately 3 000 ft/min coincident with a request for 50° flaps, and a decrease in thrust, and then decreased to about 1 800 ft/min until about 5 sec before the initial contact. Prior to initial contact, the aircraft was rotated to a virtually level attitude, the rate of descent was decreasing, the airspeed was about 191 kt, and the indicated altitude was about 900 ft AMSL. The aircraft first struck small tree limbs at an elevation of approximately 875 ft AMSL, 9 357 it short of the approach end of runway 18 and 429 it right of the extended runway centre line. After several more impacts with trees and the ground, the aircraft came to rest approximately 6 878 it from the runway and 442 ft right of the extended runway centre line and burst into flames. A stewardess who survived the accident stated that the first noticeable impact felt like a hard landing. None of the survivors recalled any increase of engine power or felt any rotation of the aircraft. The accident occurred at 2057 hours during darkness in an area where snow was falling. Five crew members and 65 passengers were killed while 12 other occupants were seriously injured.

Flight 553 was a scheduled domestic passenger flight from New York to Chicago, Illinois, with en-route stops at Harrisburg, Pittsburgh, Pennsylvania, and Dayton, Ohio. The flight departed Pittsburgh for Dayton at 1125 hours Eastern Standard Time on an IFR flight plan and was operated under radar surveillance for the duration of the flight. As the flight approached the Dayton terminal area it was cleared to descend from FL 200, its cruising altitude, to 5 000 ft, and a transfer of radar control from Indianapolis Air Route Traffic Control Centre (ARTCC) to the Dayton Radar Approach Control facility (RAPCON) was made when the flight was approximately 8 miles northeast of the Urbana Intersection on Victor Airway 12 North. The Dayton RAPCON approach controller established radio contact with the flight at 1152:36 hours. The flight was again cleared to 5 000 ft, instructed to take a heading of 240° for a vector to the final approach course (ILS) and to report leaving 6 000 ft. At 1153:22 hours, the controller cleared the flight to descend to and maintain 3 000 ft and turn left to a heading of 230'. This was correctly acknowledged by the pilot- in-command at 1153:28 hours. Immediately after the issuance of this clearance the controller observed for the first time an unidentified radar target ahead and slightly to the right of the flight and issued at 1153:32 hours the following traffic advisory: "TWA five fifty three, roger, and traffic at twelve thirty, one mile, southbound, slow moving." This was acknowledged by the pilot-in-command at 1153:36 hours. Approximately 14 seconds later, the flight and the unidentified radar target merged, separated, changed shape on the radar screen and then disappeared. At 1154:02 hours the controller advised the flight that it was clear of traffic but no reply was received. Subsequent efforts to establish contact with the flight were unsuccessful. The unidentified radar return was from a Beechcraft Baron B-55 on a company business flight, en route from Detroit, Michigan, to Springfield, Ohio. The aircraft had departed Detroit City Airport at 1101 hours on a special VFR clearance to leave the control zone 5 miles from the airport. No flight plan was filed, nor was one required. Approximately two minutes after take-off, the pilot reported on top of the smoke and haze and then left the Detroit tower frequency. No record of any further communication with any FAA communication facility or air traffic control facility could be found that related to the Beechcraft, nor was such communication required. The operator of Springfield Aviation Inc., at the Springfield Airport, testified that at approximately 1154 hours the pilot of the Beechcraft established radio contact with his office and requested a courtesy car. During this conversation the pilot stated that he would be landing shortly. There was no record of any subsequent radio contact with the aircraft. The aircraft collided at 1153:50 hours, in bright daylight, approximately 25 NM northeast of the Dayton Municipal Airport at an altitude of about 4 525 ft AMSL, and both aircraft crashed. The wreckage of the DC-9 was found in a wooded area. All 26 occupants in both aircraft were killed.

The crew was performant the calibration of the ILS system at Pittsburgh-Greater Pittsburgh Airport. While approaching from the northeast, the engine stopped. The airplane lost height, struck trees and crashed in Coraopolis, some 3 miles northeast of the airfield. All three crew members were injured and the aircraft was destroyed.

The crew (pilots and instructors) departed Pittsburgh-Greater Pittsburgh Airport at 2230LT for a local training flight (proficiency check). About thirty minutes into the flight, the crew reported an engine fire and elected to return for an emergency landing when the airplane went out of control, clipped trees and crashed in flames near the Snowden Junior-Senior High School. The aircraft was destroyed and all five crew members were killed.

The DC-4 was on a simulated ILS approach to Pittsburgh when the copilot established visual reference with the runway. The approach was continued visually but the rate of descent was excessive. The captain applied power, but before recovery was complete, the right main gear struck an embankment short of runway. Full power was applied and a go-around was carried out. Severe buffeting and a number three engine fire were experienced as the DC-4 circled for another approach. The landing was carried out safely and all 55 occupants were evacuated. The aircraft was later considered as damaged beyond repair.
