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.

(-23) While responding to an accident scene on the Florida turnpike N911HR.a BO-105 helicopter crashed on final approach to the landing site. The pilot states that when turning final he was at 300 feet and 60 knots. As he rolled onto final and stabilized the approach he saw trees in the glow of his landing light with his peripheral vision. He applied power without results. He applied additional power and appeared to accelerate toward the trees. He then tried to decelerate the a/c and applied more power and impacted the trees at approx. 60 feet above the ground and then impacted the ground on its right side. (-4)while approaching a landing area to pick up a patient the pilot stated that as he passed through 300 feet, the helicopter began to descend rapidly. He applied collective control and engine power, but the helicopter continued to descend. The helicopter collided with trees and then rolled onto the right side, coming to rest in a swampy area. He did not observe any anomalies or warning lights. Post crash examination of the helicopter structure, flight controls, engines, driveshafts, and transmissions showed no evidence of precrash failure or malfunction.
