19690604: FAA and the Central American Corporation for Air Navigation Services (COCESNA) signed a contract under which FAA would provide technical assistance for air navigation and traffic control services to COCESNA, a five-nation governmental group whose members were Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. FAA had traditionally provided technical assistance to Latin American countries under the sponsorship of the State Department’s Agency for International Development; however, this was the first time FAA provided such services to these countries under a direct reimbursable contract.
19710604: FAA issued the first supplemental type certificate approving installation of a nitrogen fuel-tank inerting system in a civil aircraft to protect against accidental ignition of fuel vapors.
