This Bo 105CBS was first flown in Germany as D-HDHX prior to delivery to MBB Helicopter Corp in the USA as N46984 and sale to the Tennessee Gas Pipeline Co. (Tenneco) as N3537T. It was originally used for offshore pipeline support and onshore patrols from Houma, LA. Tenneco became part of the ANR Pipeline Co. which El Paso Corp sold to Trans Canada Pipeline in 2007. TC replaced its Bo 105s with AW119 Koalas and N3537T was sold by GM Leasing (Arrow Aviation) to National Helicopters in Canada as C-FNHE in Dec 2010 for use on a HEMS contract in Saint Maarten. To the USA in Dec. 2023 as N525Z.

In June 2009, Trans Canada Pipeline's ANR Pipeline Company ordered three AW119s to support offshore operations in the Gulf of Mexico. The AW119s replaced MBB Bo 105s Trans Canada inherited when it bought the former Tenneco Energy pipeline from El Paso Corp n in 2007. Tenneco was one of the first Bo 105 customers in the US in 1973. N963TC was built in Philadelphia, PA and delivered to TC's helicopter base at Harry P Williams Memorial Airport, Patterson, LA in 2009.
