On January 22, 1999, after eight months of existence, PCGAG acquired its first aircraft, a BN Islander from the Philippine National Oil Company – Energy Development Corporation (PNOC – EDC). After six months of intensive inspection and rehabilitation, it was commissioned into Coast Guard service on June 26, 1999 as PCG–251. In June 1999, the first helicopter, a MBB BO-105CB was acquired from PADC and commissioned with the tail number PCG–1636. Another aircraft, a Cessna 421B "Golden Eagle" was acquired without cost from the Bureau of Soils and Water Management sometime in the early part of 2000. However, due to budgetary constraints, the aircraft rehabilitation is not yet completed to date. In the same year, another BN Islander with the tail number PCG–684 was acquired. It was commissioned and activated in June 2002 after it underwent rehabilitation. On March 30, 2001, the helm of the CGAG was transferred to Captain Lino H Dabi PCG. In search of a bigger home for its growing inventory, on November 21, 2002, with the support of Pantaleon Alvarez, the Secretary of Transportation and Communications, the Manila International Airport Authority allowed CGAG to occupy its present location. Extensive renovation work was undertaken to make the hangar suitable as the nerve center of all Coast Guard Air Operations. On March 28, 2003, the CGAG acquired another BO – 105C helicopter from PADC and was commissioned into the service as PCG – 163 during the Group's 5th Founding Anniversary.
