Killed in the tragic accident were MSP Pilot Stephen J. Bunker, 59 of Waldorf, Tfc. Mickey C. Lippy, 34 of Westminster, MSP flight paramedic; Tanya Mallard, 39 of Waldorf, an EMT-B with the Waldorf Rescue Squad; and patient, Ashley J. Younger, 17 of Waldorf. Jordan A. Wells of Waldorf was the sole survivor.

 According to Keith Holloway, NTSB on-scene spokesperson, “We are still in the process of gathering factual evidence at the scene. We expect the craft to be removed from the scene by the end of today.” Holloway indicated that the craft would be taken to another location for further investigation. “We have not determined the cause of the crash at this time.”

The helicopter crash on Sunday was the fourth such fatal incident in Maryland since 1972. Each previous crash killed a two-person crew in a Bell Jet Ranger.

Prior to Sunday’s crash, the most recent accident was in January of 1986. After the 1986 crash, Maryland adopted new, more stringent safety procedures and increased the standards for pilots with accompanying trauma medical personnel aboard. The moved led the state to purchase new helicopters. The helicopter crash on Sunday involved the second oldest aircraft in the fleet.

The details of the events leading up to Sunday’s crash have been stated as follows by NTSB:

Trooper 2 departed under visual flight rule conditions to rescue two highway accident victims near Waldorf, Md. The aircraft (N92 MD), call sign “Trooper 2,” departed the automobile accident site for Prince George’s County Hospital Center but diverted back to Andrews AFB—for reasons unknown to investigators.

The 10:55 pm Andrews AFB weather indicated visibility seven miles with a broken ceiling at 1,300 feet. The 11:55 pm FAA weather report indicated visibility at 4 miles with mist, a broken ceiling at 500 feet and scattered clouds at 200 feet. At 11:48 pm, Trooper 2 requested an ILS approach for Runway 1 at Andrews. About eight minutes later, aircraft switched to Andrews tower. Controllers cleared Trooper 2 and provided vectors for the approach to Runway 19R, which was the active runway at the time.

When the aircraft was about 4 miles out on final, the pilot told controllers that he was having trouble capturing the glide slope. The tower indicated to the pilot that the glide slope equipment was operating.

When the helicopter was about 3.5 miles out, Trooper 2 requested an airport surveillance radar approach so that controllers could talk the aircraft down. The request was acknowledged when the aircraft was about 2 miles out. That was the last known transmission. The pilot made no distress call. Maryland State Police informed the NTSB that the aircraft h
