<p>Pilots had been persistently following up with the company to replace a faulty engine since February; it was finally replaced in April after pilots wrote to Pawan Hans general manager in Mumbai</p>

Thanks to the relentless persuasion exhibited by the Pawan Hans pilots (Northern region) since February, the company finally replaced the entire engine of a Bell 407 helicopter — declared unfit by the engine manufacturer (Rolls Royce) — on April 26. While the six-seater chopper mainly ferries devotees in Kedarnath, during off-season it is despatched to Mumbai for providing joyrides. The helicopter, now equipped with a new engine, is currently in Delhi and is being readied for Kedarnath yatra.
