On 8 September 1990, King Gustav of Sweden was one of the guests with
the opening of the new plant and research centre of Ericsson Radio
Systems in Emmen, the Netherlands. The guests were flown in by KLM
Helikopters with two Sikorsky S-61N: PH-NZI #1 and PH-NZR #2. The
helicopters landed near the Ericsson facilities. The 1978-built Sikorsky
S-61N s/n 61.808 (ex. LN-OQN) was registered PH-NZR with KLM NV,
operated by KLM Helikopters BV, on 3 April 1986. The PH-NZR was mainly
used on Offshore flights first out of Amsterdam Airport Schiphol, later
out of Den Helder-De Kooy. In 1991, Rowan Companies Inc., owner of ERA Aviation Inc., bought 49% shares of
KLM HelikoptersBV and the company was renamed KLM ERA Helicopters BV.
On 12 October 1993, the PH-NZR was registered with KLM ERA Helicopters. Between mid 1994 and mid 1995, the
PH-NZR participated as part of the United Nations peacekeeping force as UN191 in
Croatia as replacement of the damaged Sikorsky S-61N PH-NZD.
In 1997, Schreiner Luchtvaart Groep BV bought the 51% shares of KLM in KLM/ERA Helicopters BV.
On 30 January 1998, Rowan Companies Inc., announced that it has terminated
its 49% interest in KLM ERA Helicopters and sold to Schreiner Luchtvaart Groep BV. As payment for their shares in KLM/ERA Helicopters BV,
Rowan Companies Inc. has received a distribution of assets consisting of cash, two Sikorsky S-61N helicopters, including the PH-NZR,
spare engines and parts. The equipment would be utilized by the Company's subsidiary, Era Aviation, Inc. As a result of this
transaction, the PH-NZR was registered to Rowan Drilling Aviation (Netherlands) BV in Badhoevedorp, on 11 February 1998.
The same day, registration PH-NZR was cancelled and the helicopter was registered temporary N563EH in the USA on 12 February 1998. On 18
February 1998, the helicopter was registered as N563EH with ERA Aviation Inc., Anchorage, AK, USA. Since, the registered owner changed to
ERA Helicopters LLC, Lake Charles, LA, and registration N563EH was cancelled as exported to Brazil on 15 December 2008. In Brasil the Sikorsky
S-61N2 was registered PR-AEL with Aeroleo Taxi Aereo Ltd., Rio de Janeiro, as operator and ERA Helicopters LLC as owner. Registration
PR-AEL was cancelled on 5 November 2011.
