First Upgraded RNZAF 757 Returns to Service

The first of the RNZAF’s Boeing 757s (NZ7571) to be upgraded by Mobile Aerospace Engineering in Alabama has been completed and returned to RNZAF service. It arrived back in New Zealand on the 4th of August after 16 months’ work in the US.

By the end of 2008, both of the RNZAF’s 757s will have completed upgrades that will significantly increase their capabilities as multi-role transport aircraft for the service. The 757 was previously configured as passenger aircraft with only limited freight capability. The modifications involved adding a large front cargo door and have transformed the aircraft into a full “combi” version, offering multiple freight/passenger configurations, strengthening the cabin floor and adding a cargo handling system (including a 9G cargo net).

In addition to their fuselage and cabin interior modifications, the aircraft’s mission equipment has also been upgraded. Modifications to mission equipment include: engine management systems, external air stairs, crew access ladder, navigation systems and communication equipment.

The RNZAF describes the 757’s role as “inter-theatre airlift”, which incorporates deployment and support of New Zealand armed service personnel to places like Afghanistan, movement of people and/or aid in emergencies such as the Indonesian tsunami, aeromedical evacuation and VIP transport. All of the modifications involved in the upgrade will enhance these various functions.

The aircraft’s Rolls Royce RB211engines have been upgraded to E4B standard, which provides an additional 2,400 lbs thrust and allows operation from shorter runways. The upgraded engines each now provide 42,700 lbs thrust.

In its full freight configuration, the 757 has a freight payload of 23,000 kg and a range of 2,500 nm. In VIP configuration, carrying 20 passengers, its range is around 3,500 nm.

The total cost of the modifications to both aircraft is around NZ$112 million.
