scope:

The purpose of this part of the Standard is to provide certification requirements for the design of new rotorcraft for operations in the UK military operating environment. It may also be used for the certification of significant or changes (modifications) and specialist conversions, for example, transport, light communications, patrol, non-combat training rotorcraft and specialist conversions, eg target tug. Foreign military derivatives of civil rotorcraft certificated to civil requirements fall within this category. An acceptance procedure is necessary for such rotorcraft against their proposed military roles, and to determine to what extent certification procedures would be affected by configuration or other changes, eg increased operating weights, in the military roles envisaged.

Unless otherwise specified in this Standard, the certification requirements of EASA CS 29 (Amendment number as stated in the revision notes above), including related AMC and Appendices, shall be applied. In addition to the requirements of this Part of Def Stan 00-970, users must also include relevant requirements contained in Part 11 and Part 13.

Military rotorcraft may be derivatives of civil rotorcraft certificated to the civil BCARs, FARs, JARs or CSs current at the time of design or certification. There are, however, certain basic differences in the civil requirements from these sources and the military requirements of Def Stan 00-970. This Standard has been produced by reference to the CS 29 with additional military requirements (designated 'UK 29') derived from, or referenced to other parts of the Def Stan 00-970. It is required that, when the TCB is produced for a rotorcraft which is to be certificated against this Standard that all the requirements contained herein are evaluated for applicability and any additional requirements are included as Military Certification Review Items (MCRI) to reflect the military role, usage or special design features.

Def Stan 00-970 requirements contain design and airworthiness certification requirements and recommendations for military derivatives including those covering flight testing. The EASA specification (CS 29) on which this Part 7 is based is focussed on airworthiness requirements, with appropriate AMC. Care has been taken in the production of this Standard to ensure that the requirements are consistent, any clarification or advice on its application should be sought from the MAA ADS team. Note that where CS 29 refers to 'the Agency', this should be considered to mean the certifying authority.
