II.2.4) Description of procurement: UKRI wishes to establish a Contract for the provision of Twin Otter Maintenance programme.

NERC/BAS has a requirement for the provision of Engineering services, (Airframe, Engine, Avionics and Design,) relating to the maintenance and servicing of:

Four Viking DHC6-300 (Twin Otter) aircraft (increased MTOW), wheel ski equipped when necessary, in science/survey/cargo roles

The aircraft are the property of NERC, operated by BAS, for the purpose of supporting the NERC’s Air Operation, with a contract placed with the Selected Contractor for the continuing maintenance of the aircraft in all theatres of operation. BAS reserves the right to approach and use individual short term contracts for ad-hoc support, where use of a more local service provider is more appropriate/efficient or cost- effective.

A quantity of spare parts, ground support equipment, special, and general tooling is held by BAS in the Antarctic and UK. The Contractor will be responsible for the supply of any additional equipment and spares the Contractor deems necessary. The latter additional equipment is to be held on a consignment basis until used in support of the NERC aircraft.

The four DHC6-300 aircraft are registered in the Falkland Islands. The oversight of maintenance is by Air Safety Support International (a wholly owned subsidiary of UK Civil Aviation Authority). The regulatory framework for Maintenance Organisations is the Overseas Territories Aviation Requirements (OTAR 145).
All four aircraft have an STC for operations at 14,000lb. In the Antarctic and Arctic they are operated on wheel/skis. Two of the platforms are heavily modified to undertake airborne science missions.

The contract is both for heavy maintenance at the contractors home maintenance facility and line maintenance when the aircraft are deployed.
The aircraft are deployed to the Antarctic in October. It is expected that up to 4 licensed engineers will support the aircraft depending on the field programme and deployments. They undertake support of both the UK and international science programmes from the research station at Rothera. The facilities at Rothera include a Hangar and workshop facility. The support includes Halley Station and field work is conducted across the whole Continent. An engineer will sometimes be deployed with the aircraft, dependant on location and duration of the deployment, and need to be stationed at remote field camps. The deployment of the four aircraft to the Antarctic is for approximately 6 months with a return to the home maintenance facility in March for heavy maintenance.
Whilst undertaking heavy maintenance the contractor will often be requested to incorporate modifications in support of operation equipment upgrades but also science requirements.
