With The Robinson R-44’s Safety Issues, The FAA Has Taken a More Hands-Off Approach, Kim Christensen, LA Times, November 18, 2018. The FAA finally responded to this problem as it usually does-not by correcting the equipment issue but by focusing on the pilot, issuing Special Flight Regulation 73, which required extra instruction for Robinson pilots. The rotor system leaves the aircraft, which means the aircraft is no longer capable of flight, but as it does so, it often slashes through the cockpit with obvious fatal results. At the time, it was the only known accident in which someone survived an in-flight rotor separation due to mast bumping–only because the test protocol required the wearing of parachutes.īut the fatality in the Pax River AH-1 crash was consistent with what can occur in Robinson mast bumping events.

Navy Test Pilot School which cost the life of one of the two aviators on board. In the 1980’s, I handled a mast-bumping case which occurred at the U.S.

In fact, a reporter for the Fort Worth Star Telegram, Mark Thompson, won a Pulitzer Prize for his series on this phenomenon. The Bell products were notorious for this phenomenon during combat operations in Viet Nam which often necessitated radical maneuvering to avoid enemy fire. It can happen almost instantaneously–before the pilot can react. This can occur during drastic maneuvers or during turbulence or if the pilot reacts less than correctly to an in-flight emergency such as an engine failure. The gravest hazard associated with teetering rotor systems is mast-bumping, where the heavy main rotor hub leaves its normal plane of rotation and actually smashes into the mast, causing the mast to break and the rotor system to depart the helicopter, which means the helicopter is now an aircraft without wings. This is a somewhat antiquated “semi-rigid” system but has been used most widely by Bell Helicopter on its UH-1 “Hueys,” its Bell 206 OH-58 “Jetrangers,” and its earlier AH-1 “Cobras.” More modern helicopters, such as Airbus and Sikorsky, and now even Bell, utilize a “fully articulated rotor system,” where, instead of “teetering” to absorb loads, the rotor blades are allowed to “lead” and “lag” on a hinge where the blade attaches to the hub. Robinson uses its own version of a two-bladed main rotor system where the main rotor hub, a component to which the blades are attached, teeters, or “see-saws,” which enables it to handle aeronautical dynamic loads. from 2006-2016, more than any other civilian helicopter, which translates into 1.6 deadly accidents per 100,00 hours flown, a rate nearly 50% higher than the other common civilian helicopters tracked by the Federal Aviation Administration (FAA). Its staggering premise: the Robinson R44, the world’s best-selling civilian helicopter, has been involved in more than 42 fatal crashes in the U.S. The article is well-researched, has helpful graphics, and is worth a read. “Because the aircraft are all similar dynamically and structurally with the same rotor systems and, until recently, fuel tanks, they all pose the same risks to their pilots and passengers,” Anderson states.Īnderson’s opinions are supported by numerous news stories, none more thorough than Danger Spins From the Sky, a November 2018 article by Los Angeles Times reporters Kim Christensen and Ben Welsh /. Depending upon which aviation expert you talk to or how accident rates are spun, its accident history is attributed to Robinsons being terribly deadly machines often operated by inexperienced/risky pilots-or some combination of faulty machine and pilot.Īviation attorney Joseph Anderson, who has represented victims of several of these fatal crashes, lists four major problem areas with all versions of the Robinson helicopters (1) mast bumping, where the aircraft’s teetering (see-saw) rotor system contacts the mast causing rotor system separation, (2) delamination of the rotor blades where the blades actually come apart, (3) aluminum fuel tanks which split open on impact causing post-crash fires, and (4) low inertia rotor system which allows for rapid loss of rotor rpm during powered-off situations. The Robinson Helicopter line, consisting of the original, two-seat introductory R-22, the four seat R-44, both piston-powered, and the R-66, a four-seat turbine-powered version, have a history of fatal and non-fatal accidents. Tragically, according to the NTSB, this was yet another in-flight breakup, the cause of which remains undetermined. The National Transportation Safety Board (NTSB) has just released its Preliminary Report (PR) on yet another Robinson Helicopter fatal crash, this one involving a Model R66 which took the lives of two citizens of Buffalo, New York, Pilot Mark D.
