What's it all about?

OM Parts A, B, C and D

Regulatory requirements regarding Operations Manuals are vast and extensive effort is essential for seamless compliance. Legal requirements and liability issues demand that operators ensure their documentation matches the far-reaching EASA regulations at all times.

  • OM Part A is not aircraft type-related and covers all operational procedures ensuring a regular and safe operation.
  • OM Part B contains aircraft type-related procedures and company instructions with regard to the operation of specific types of aircraft.
  • OM Part C comprises navigational charts and other route and aerodrome information related to the geographical area of operation.
  • OM Part D includes all training related information and rules.

TRS Aviation Consulting has broad experience regarding all matters concerning Operation Manuals and our team of aviation specialists will find a tailored solution matching your needs. Our services include the creation of entirely new Operation Manuals, reviewing and updating of existing manuals and ongoing revision services. We monitor regulatory changes that impact your operation and inform you instantly should upcoming changes affect your business.


Minimum Equipment Lists (MEL) allow for aircraft operation in certain non-standard configurations as permitted by approved documentation.

While being based on the aircraft type related Master Minimum Equipment List (MMEL), the MEL has to be tail sign-specific, requires corresponding operational and maintenance procedures and needs regulatory approval from the Competent Authority. It is the operator's responsibility to develop an MEL containing the related operational and maintenance procedures in consideration of the given flight operations and the given operational conditions.

TRS Aviation Consulting experts will take care of all of your MEL (and CDL) related needs and consult you in any negotiations with affected authorities.


Any non-commercial operators operating complex motor-powered aircraft registered in an EASA member state or having their principal place of business in an EASA member state have to comply with Part-NCC regulations since August 2016.

Affected operators need to

  • Establish a management system;
  • Create an Operations Manual;
  • Create a tail-sign specific Minimum Equipment List (MEL);
  • Nominate persons as applicable to the operation;
  • Assign the aircraft to a Continuing Airworthiness Management Organisation (CAMO);
  • Show compliance by establishing an audit plan;
  • Provide declaration to the Competent Authority.

TRS Aviation Consulting will offer their extensive experience regarding EASA regulatory requirements and successfully guide you through the entire process of becoming and remaining compliant with Part-NCC.

Management System (SMS/QMS)

EASA rules require air operators to establish, implement and maintain a multilayered management system managing safety and compliance of the operation. An effective management system identifies responsibilities and accountabilities of key staff members, documents key processes and helps to identify hazards and associated risks that could affect your organisation.

TRS Aviation Consulting will create a customised Safety Management System tailored to the scale of your organisation and will guide you through the process of implementation.

Organisation Management Manuals (OMM)

Depending on the complexity and size of their operation, for some flight operations establishing a management system and creating a related Organisation Management Manual might be mandatory. Whether a full management system is required to be compliant with the regulations or if appropriate checklists and the documentation of processes might be sufficient, depending on the complexity of your operation.

TRS Aviation Consulting will find adequate solutions to improve your operational business.
