N351SD

This entry covers rotorcraft airframe N351SD, a Bell UH-1H Iroquois built in 1968 with manufacturer serial number 10713. The helicopter is operated by the Pakistan Ministry of Interior (Air Wing) — operated following U.S. Dept. of State transfer and was placed under their jurisdiction in Quetta, Pakistan after the documented transfer. Registration for the aircraft is US, and its operational history for this airframe includes the notable diplomatic transfer arrangement under which it was supplied. Valuation and specific condition assessments for this individual airframe are Not published.

This airframe is fitted in a utility / troop transport configuration with a typical bench and side-facing military layout accommodating up to 15 occupants, optimized for personnel movement and internal load flexibility. Avionics fit are consistent with UH-1H utility operators of comparable vintage—basic flight instruments and mission radios appropriate for transport and liaison duties—while specific avionics lists for this serial are Not published. Based at Quetta under the operating authority noted above, typical missions for N351SD would include internal security transport, personnel insertion/extraction, logistics support, and short-range liaison flights within Pakistan, exploiting a cruise speed of 114 kts and a maximum practical mission radius given a 276 nm range. Maintenance considerations for this airframe reflect UH-1H norms: adherence to T53-L-13 powerplant service intervals, airframe corrosion control for older examples, and parts logistics influenced by legacy Bell supply chains.

The Bell UH-1H Iroquois family occupies a long-established niche as a rugged, versatile utility rotorcraft valued for troop transport and general utility roles. Powered by the reliable T53 series, the type competes functionally with other medium utility helicopters of its era rather than modern turbine designs; contemporary alternatives include later-model utility helicopters for buyers seeking greater payload or modern avionics. For operators and prospective buyers, maintenance history, availability of T53-L-13 components, and export/import/regulatory status following a U.S. Department of State transfer are primary considerations for operational continuity and resale.
