Because of its unique ordnance or operational requirements, military aircraft has potential risks different from civil aircraft. This explains why there is no global document for military airworthiness and each nation has its own sovereign authority. But harmonized airworthiness activities among authorities are required to reduce cost and time for recent multinational programs. In this study, we show the airworthiness policy of the European Military Airworthiness Authorities and U.S. DOD Authorities which facilitate recognition of certificates and approvals issued by any other authorities. And we propose future works for Korea military airworthiness society to develop organizational recognition system.

This is a study on the effective and efficient way of airworthiness certification for Korean indigenously developed military aircrafts. Investigating the policy, process, and capability for military aircraft airworthiness certification in USA end Europe, the approach for Korean military aircraft airworthiness certification is recommended. Using FAR as basis for military airworthiness criteria is much more beneficial in initial stage of establishing airworthiness certification system. And all the available resources regardless of civil or military institutes need to be cooperated to accomplish required level of indigenous airworthiness certification capability.

This is a study on the establishment of airworthiness certification system fitted for korean military aircraft acquisition and export. Based on the investigation of US civil & military airworthiness system and analysis of the real state of domestic military aircraft acquisition, this paper offers some ideas that can be helpful to establish laws and organizations to certify airworthiness. Particularly this paper suggests that the best way to build airworthiness certification laws/guidelines and technical criteria, the optimal organizational structure which is decentralized by dividing administrative certification authority and technical research center.

This is a study on the propulsion criteria for airworthiness certification of the military aircraft. This treatise described the introduction of the airworthiness certification system, the features and difference between the military and commercial aircraft, the introduction of the standard airworthiness certification, the important technical criteria, and the several application instances of the criteria.

Airworthiness certification is a government certification for the military aircraft to safely attain, sustain and terminate flight and It is a mandatory process of qualifying the flight safety within the operational boundaries of a military aircraft. To save the manhour, time and cost for applying all the airworthiness certification criteria to the aircraft equipped with flight control switching mechanism development program, an identification of the risk and systematic assessment of risk is analysed. Airworthiness redesign actions so called software switching mechanism for the modified aircraft in the flight technology and electric system area are suggested to reduce the risk hazard index.

In modern society, the use of small rotary-wing unmanned aerial vehicles such as drones is increasing. As the military considers tactics using drones, demand for drones is increasing. However, there is still no airworthiness certification standard for drones for safety. In this paper, we proposed airworthiness certification standards for small rotorcraft unmanned aerial vehicles based on CS-LURS in Europe and STANG-4703, 4738 (draft) of the North Atlantic Treaty Organization. In addition, airworthiness certification standards have been strengthened through the case of unmanned aerial vehicle accidents in operation by the Korean military. The airworthiness certification standards for small rotary-wing unmanned aerial vehicles will be supplemented through a demonstration project.

For operating military aircraft, military certificate of airworthiness (MCA) must be obtained from military authority. Among procedures of general airworthiness certification, there is a military type certification process that aircraft design complies with military airworthiness certification criteria. The Surion is the first military rotorcraft which has obtained military type certificate, production validation and airworthiness certificate in Korea, and the Surion derivatives for special mission are being operated for government services. Based on Aviation Safety Act, in order to operate the Surion derivatives (military aircraft) for special purpose (such as emergency patient transportation and firefighting), the issuance of special airworthiness certificates was needed from civil airworthiness authority, and the restricted category type certification (RTC) is one of design approvals for special airworthiness certification to be streamlined. This study discussed the procedures for acquiring RTC for special purpose operation of the Surion derivatives classified as military derived aircraft, and suggested procedural ideas to improve Korean RTC system.

Unmanned Aircraft Systems (UAS) are rapidly emerging not only as a key military power, such as surveillance and reconnaissance for military purposes but also as a new air transportation means in the form of Urban Air Mobility (UAM). Currently, airworthiness certification is carried out focused on the verification of technical standards for flight safety suitability of aircraft design in accordance with the Military Aircraft Flight Safety Certification Act and does not employ the model for operational risk assessment for mission areas and airspace. In this study, in order to evaluate the risk of the mission area from the perspective of the UAS operator, a risk assessment simulation has been conducted by applying the Specific Operations Risk Assessment (SORA) model to the operating environment of the Korean military UAS. Also, the validity of the SORA model has been verified through the analysis of simulation results, and a new application plan for airworthiness certification of the military unmanned aerial system has been presented.

Airworthiness certification of military aircraft is a government's certification that it must have airworthiness and ability to demonstrate its requested function and performance. NATO released STANAG-4671 to establish the minimum airworthiness requirements for UAVs between 150kg and 20,000kg MTOW in 2009. Up to now, there are no clear airworthiness certification criteria and guideline for small UAV which is less than 150kg. STANAG-4671 is used for military UAV airworthiness certification in Korea as Other Airworthiness Certification Criteria. However, since STANAG-4671 requires the same Target Level of Safety without regard to MTOW, excessive Target Level of Safety or design requirements could be applied to relatively small-medium UAV. In this paper, classification and criteria of airworthiness certification for military UAV were investigated and a Target Level of Safety was analyzed based on MTOW using ground victim criteria.

The world is currently confronted with regional conflicts among nations that seek to protect their territory. The associated counter-terrorism activities and international business flows can be increased through airworthiness-recognition tasks that are related to aircraft exports, dispatch troops, and overseas bases. It is important to establish airworthiness-recognition processes between foreign military authorities to minimize the potential for sovereign national positions and responsibilities. For this study, the military airworthiness recognition between recognition partners was surveyed to secure flight safety for the development and operation of aircrafts. The analysis of the U.S. and European Military Authority Recognition Questionsets (MARQs) in this paper introduces the rules, inspection capabilities, production process, and certification of the airworthiness authority. The regulatory activities, which are required by the Korea Military Airworthiness Authority (MAA) with respect to foreign MAAs, can be reduced by the implementation of the MARQ.
