Petroleum Helicopters operated Aerospatiale SA330J Pumas between the late 1970s and 1988 servicing offshore drilling rigs in the USA. N3601U was photographed at PHI's Morgan City heliport on the shore of Lake Palourde, which was known as the world's largest heliport when PHI opened it in 1969. After flying in Ecuador as HC-BPD in the late 1980s, PHI sold it to Air Zermatt where it became HB-XUB in June 1989. It was written off on Sep. 11, 1989 when it crashed after both engines failed while lifting an external load near Blauherd. PHI lost four of its Pumas in fatal accidents in 1978-1988.

A bare two month after this picture was taken, N748P suffered a fatal accident on January 4, 2009 with eight of the nine persons on board being killed. Cause of the accident was a birdstrike (red-tailed hawk) fracturing the windshield and interferring with the engine controls, resulting in the loss of power to both engines from which the crew was unable to recover. A similar incident happened to S-76 N276TH in 1999.

Delivered new to PHI in April 2007. Later re-registered to N779PD. Now with Lahak Aviation as 4X-BEY, based in Haifa.

Third S-92 for PHI, manufactured in 2005. Re-registered to N392R in October 2016 and subsequently transferred to Ghana in Westafrica, from where it still serves PHI as 9G-... (N392R got cancelled from the FAA register in October 2020).
