Carlisle, Pa. — Federal investigators said Friday they recovered intact data cards from a state police Bell 407 helicopter and a Cessna 150 that collided at a small central Pennsylvania airport, an advance that could yield vital clues in the probe of the crash that killed the Cessna pilot.
What investigators found
National Transportation Safety Board investigator in charge Aaron McCarter described the recovery of the memory cards as "very good news from a data standpoint." The cards will be examined over the weekend as the agency works to determine how the small plane struck the helicopter’s tail during a Wednesday night operation at Carlisle Airport, about 110 miles northwest of Philadelphia.
"We don't know exactly what kind of parameters are on these data cards, but in some cases we get fortunate," McCarter said during a briefing.
Neither aircraft was required to carry full flight data recorders or cockpit voice recorders. Still, many modern avionics units and aftermarket devices store useful telemetry on removable media — information that can show control inputs, engine parameters and trajectory data.
Crash details and immediate findings
The Federal Aviation Administration identified the aircraft as a Bell 407 helicopter operated by Pennsylvania State Police and a Cessna 150. Authorities say the Cessna was on approach to land when it veered and struck the helicopter's tail. The Cessna pilot died; two people aboard the helicopter were treated for injuries.
McCarter said both pilots were flight instructors and that investigators have substantial evidence the Cessna pilot was aware of the helicopter's presence. Video of the encounter reviewed by an aviation analyst suggested the small plane may have suffered a flight control or mechanical problem that caused it to depart the intended flight path.
"I believe (the Cessna was) experiencing some type of flight control problem or mechanical problem of some sort," an expert who reviewed crash footage said.
Local impact and investigation steps
The crash disrupted operations at the local airport and has drawn attention from aviation safety officials statewide. Investigators will analyze the recovered cards, air traffic communications, maintenance records and the pilots' recent activities to reconstruct the sequence of events.
- Aircraft involved: Bell 407 helicopter, Cessna 150
- Casualties: One fatality (Cessna pilot), two injured (in helicopter)
- Location: Carlisle Airport, Cumberland County
| Item | Detail |
|---|---|
| Proximity to runway | Helicopter hovering ~30–50 feet from runway, per investigators |
| Pilot qualifications | Both pilots held flight instructor credentials |
The NTSB typically publishes a preliminary report within days to weeks, followed by a final report that may take months. That final document will assess probable cause and recommend safety actions if warranted. For local officials and air operators, findings could affect training, hover‑operations procedures and airport traffic coordination.
State police and federal agencies continue to collect evidence at the scene and interview witnesses. Authorities have not released the names of the victims pending family notification.
Local residents and pilots using small regional airports often point to the risks inherent in mixed operations — powered fixed‑wing traffic and rotorcraft — especially during training activities near active runways. The data recovered from the two aircraft could help determine whether a mechanical failure, a misjudgment during approach, or some other factor led to the collision.
