The Boeing 737-200C operating into Puvirnituq Airport (CYPX) in Nunavik, northern Quebec, represents one of the most specialized niches in commercial aviation — gravel-strip jet operations in Canada's Arctic and sub-Arctic regions. The video captures two defining characteristics of the 737-200 in this environment: the activation of its distinctive clamshell (target-type) thrust reversers on landing rollout, and the gravel runway surface that makes this operation categorically different from mainline jet service. CYPX serves the Inuit community of Puvirnituq on the eastern shore of Hudson Bay, with a roughly 6,000-foot gravel strip that is accessible year-round only by air. The "C" designation indicates a Convertible configuration, allowing the aircraft to carry a mixed load of passengers and cargo — a critical feature for remote community resupply in the Canadian North.
The 737-200's gravel capability stems from a Boeing-certified modification package developed specifically for frontier operations. The gravel kit includes vortex dissipators and inlet deflectors on the JT8D engines to prevent FOD ingestion, reinforced fuselage belly skin, modified nose gear with a gravel deflector, and special tire configurations. These modifications allow the aircraft to operate from unprepared or semi-prepared surfaces without the catastrophic FOD risk that would affect unmodified turbofan engines. The clamshell reverser design of the JT8D — which closes two doors over the exhaust nozzle to redirect thrust — is particularly suited to this environment because it does not draw air inward from the nacelle surface during reverse operation the way cascade-style reversers do on modern high-bypass engines, reducing the risk of ingesting surface debris during the high-thrust, low-speed deceleration phase.
Air Inuit is the primary operator of 737-200 Combis into Nunavik communities, including Puvirnituq, and has built an operational culture around this specific aircraft type and its unique demands. Pilots flying these routes must be proficient in gravel strip procedures, including assessing runway condition reports for loose aggregate, managing reverse thrust to avoid excessive gravel scatter and FOD damage to the aircraft itself, and operating within weight and performance limitations that are further constrained by elevation, temperature, and surface friction variables unlike anything encountered at paved-airport operations. Crew resource management on these routes also incorporates remote divert planning, as alternates may themselves be gravel strips with limited services.
The continued operation of the 737-200 on routes like CYPX highlights a significant gap in modern aviation's capability set: no current-production narrow-body jet holds a certified gravel kit. Boeing never developed one for the 737 Classic, NG, or MAX series, and Airbus has not pursued gravel certification for the A320 family. This means that when existing 737-200 airframes eventually reach the end of their economic or airworthiness life, operators serving unpaved Arctic and sub-Arctic strips will face a genuine capability crisis. Some operators have explored turboprop alternatives like the Dash 8 or ATR series for community service, but these aircraft cannot replicate the payload, range, and schedule reliability of a jet Combi on longer trunk routes within the region. The 737-200's longevity in these markets is therefore not nostalgia — it is a direct consequence of there being no certified replacement that does the same job.
