The Namibia Civil Aviation Authority (NCAA) has extended to 13 November 2026 the deadline for bids to provide flight calibration services for its navigation aids over three years. The open international bidding process, issued on 30 September 2026 and originally due to close on 30 October, is open to Namibian and international bidders, with a closing time of 11:00.
The contract covers flight inspection of instrument landing systems (ILS) and VOR/DME installations at six locations: Hosea Kutako International Airport, Walvis Bay International Airport, Grootfontein, Keetmanshoop, Ondangwa and Lüderitz. The ILS installations on runway 26 at Hosea Kutako and runway 27 at Walvis Bay are to be flight tested every six months and all other navigation aids annually, with inspections scheduled for April and October in each year from 2027 to 2029. Although both ILS installations are Category III equipment, they are operated and inspected as Category I.
Bidders need at least five years’ experience in similar services, an air operator certificate from the state of registry, a flight calibration team certified by a reputable civil aviation authority and an airworthy multi-engine inspection aircraft capable of safe one-engine-inoperative flight, equipped for night and instrument flight and flown by two pilots. Flight inspection must follow ICAO Doc 8071, using differential GPS for position reference, and bidders must provide a business continuity arrangement, such as a backup calibration aircraft, so that scheduled inspections are not interrupted by aircraft unserviceability.
The successful bidder must be certified, or willing to be certified, as a calibration service provider under NAMCAR Part 171, undergo certification by NCAA’s Air Navigation Services Safety Oversight department and obtain a foreign operator permit. Technical proposals must score at least 70 out of 100 to proceed to financial evaluation. Prices are quoted in Namibian dollars without price adjustment, bids must remain valid for 180 days, and electronic bidding is not permitted. The documents are available from NCAA’s website, and the Procurement Management Unit can be contacted at an.aacn@UMP.
