Accident
changeFlight 1526 took off from Dayton Wright Brothers Airport (MCY) headed for Akron-Canton Airport (CAK). The flight's cruising altitude was 17,000 feet (5,180 metres).
While descending to 13,000 feet (3,960 metres), the Captain checked the weather with the control tower. They reported winds at 290 degrees at 07 knots, visibility of 2 km, and temperature at 09 Celsius, but with unpredictable weather.
As the crew descended at 9,000 feet (2,740 metres), the controller reported the visibility changed at 1.5 mist, weather condition 600 feet broken, and temperature 11 Celsius.
Six minutes from landing, the crew got a new distraction. A flight instructor was teaching another pilot how to land in bad weather on the same runway as Flight 1526. The controller held Flight 1526 on the approach and requested heading 360, reducing speed 170 knots, and maintaining 3,000 feet which they required to hold their course and delay their descent. After two minutes further delay on runway 25 localizer, Flight 1526 was cleared to land. The crew was notified that the Piper had landed safely on the runway and the pilots were now ready to land. While approaching on the runway, the crew checked the final preparations onto the runway 25 localizer. Two miles from the runway, the pilots were still searching when the visibility got worse. They had to maintain a safe minimum descent altitude until the pilots could see the runway. The plane then broke through thick clouds, allowing the pilots to see the ground clearly. With the plane still approaching and still looking for the runway, they had descended very steeply. Below the minimum descent altitude, the First Officer tried to push the throttle up, then the stick shaker and aerodynamic stall warning sounded. Within the final moments of the flight, the plane crashed into two-story residential building and exploded.
Accident report
changeThe MDA for the localizer performance version of the AKR RNAV GPS 25 approach was 1,520 ft msl, and the height of the MDA above the TDZE for the lateral navigation version of the approach was 501 ft.[2]
Within reading from the approach chart, it showed 2 ways to make a same approach on the runway. The first way on the landing approach was 1,520 feet sea level below from the MDA. The second showed 501 feet above the ground in a same difference of a height which needs to require to have a higher distance altitude during the final approach onto the runway.[3]
Investigation
changeRecordings and interviews with the colleagues of the pilots showed that the pilots were overly tired at the time of the accident. They had only slept about six hours a night on average during the previous nights.
The pilots were extremely tired during the flight and they lowered the aircraft below the safe altitude of 473 feet. They could see the ground but still could not see the runway. As they searched for the runway, they failed to see that the airspeed had dropped to 98 knots, causing an aerodynamic stall and crashed into two-storey residential building.
