A brief history about the Office for Transportation Security (OTS) - which traces its origins from the National Action Committee on Anti-Hijacking or NACAH. The 1976 hijacking of a Philippine Air Lines BAC-111 plane from Zamboanga, which resulted in the death of 10 passengers and three (3) hijackers, ushered in the creation of the national Action Committee on Anti-Hijacking (NACAH), through the issuance of Presidential Letter of Instruction Number 339 on April 28, 1976, with the Secretary of National Defense as Chairman.
Because of the enactment of RA 6975 in December of 1990, the chairmanship of the NACAH was transferred from the SND to the Secretary of the Department of Interior and Local Government (DILG) through Executive Order No. 452 issued on April 5, 1991.
On May 18, 1995, EO 246 further reconstituted NACAH into National Action Committee on Anti-Hijacking and Anti-Terrorism (NACAHT) in response to the need to monitor the activities of the suspected terrorists and to develop the capabilities of local law enforcement agencies to contain the threat of terrorism.
However, to forestall confusion that will arise with the overlapping functions of the Philippine center for Transnational Crime and the National Action Committee on Anti-Hijacking and Anti-Terrorism, EO 336 was issued on January 5, 2001, which reconstituted NACAHT into the National Council for Civil Aviation Security (NCCAS), this time to provide and establish a more effective mechanism primarily contain aviation-related terrorist acts.
The Terrorist attacks of September 11, 2001 necessitated key changes to the air travel industry which saw heightened security. Among there requirements was the need to comply with the Standard 3.1.2 of the ICAO Annex 17, Amendment 11 which provides that “Each Contracting State shall designate and specify to ICAO an appropriate authority within its administration to be responsible for the development, implementation and maintenance of the National Civil Aviation Security Programme.”
In 2004, two (2) Executive Orders, EO 277 and EO 311 were issued which created the Office for Transportation Security (OTS).
