Tomanggong Airport (TMG)

Tomanggong Airport (TMG/WBKM) is a decommissioned airport facility located in the Tomanggong area of Kinabatangan District in Sabah, Malaysia, formerly serving the remote plantation estates of southeastern Sabah. Situated at coordinates 5°24'N, 118°39'E with an elevation of 26 feet above sea level, this small airfield historically provided essential aviation services for palm oil plantation operations and remote community access in one of Sabah's most isolated regions along the Kinabatangan River corridor.

The airport featured a single runway designated 11/29, operating under strict directional procedures that permitted landings only on runway 11 and departures exclusively on runway 29. This operational constraint was likely implemented due to surrounding terrain features, obstacles, or prevailing wind patterns typical of airfields constructed within dense plantation environments. The runway infrastructure was designed to accommodate small regional aircraft suitable for short-haul operations connecting remote plantation areas to major population centers.

Terminal facilities at Tomanggong Airport were minimal, reflecting its primary function as a plantation and emergency services airfield rather than a commercial passenger facility. The basic infrastructure included essential aviation services for scheduled flights operated initially by FlyAsianXpress from Sandakan Airport, providing vital connectivity for plantation workers, management personnel, and essential supplies transport to the remote Tomanggong estate areas managed by Hap Seng Plantation Holdings Berhad.

When MASwings assumed operations from FlyAsianXpress, the carrier discontinued the Sandakan-Tomanggong route due to economic viability concerns and infrastructure limitations. The airport's remote location, accessible only via estate gravel roads belonging to Hap Seng Plantation's Tomanggong Group of Estates through Tagas Estate and Litang Estate from the Sungai Segama Group via ferry crossing, presented significant operational challenges for sustained commercial aviation services.

Currently, Tomanggong Airport remains decommissioned with no scheduled commercial airline operations or active terminal services. The facility's closure reflects broader changes in Sabah's aviation network and the economic challenges of maintaining aviation services to extremely remote locations. No plans exist to restart air services to Tomanggong, as alternative transportation methods via road networks and ferry crossings now serve the plantation communities, though the airstrip may still be maintained for emergency or charter operations as required by the plantation operations.
