A safety case the TAA can sign

The MAA does not want a folder of reports. It wants an argument that this air system is acceptably safe, and the evidence underneath it. CertProve builds both from your programme

What this regime costs you today

Each Regulatory Article is reissued on its own clock. Cite one without its issue and you are quoting text that has moved.

The regulation moves under you

Every Regulatory Article is reissued on its own timetable. Your last submission may already quote text that has changed.

A folder is not a case

Reports prove things. Somebody still has to argue why the whole air system is acceptably safe, and defend it.

The hazard log outlives the team

It is read years later by people who were not in the room when the risk was accepted.

Two authorities, one aircraft

The design side recommends and the TAA releases. Each wants a different document, built from the same truth.

Whatever you fly, it has to be proven

The MRP reaches every UK military air system, and what it carries

  • Combat air
  • Air transport
  • Air to air refuelling
  • Airborne surveillance
  • Attack helicopter
  • Maritime helicopter
  • Support helicopter
  • Remotely piloted
  • Small uncrewed
  • Weapons and stores

What changes when the evidence derives itself

Citing what is in force

todayan article number copied from the last submission
hereevery article named at the issue it is on, read from the file the MAA publishes

Making the argument

todaya folder of reports, and a narrative written last
herea structured safety argument, with an unsupported branch shown as unsupported

Keeping the hazard log

todayhazards, acceptances and names scattered across tools
hereeach hazard held with its acceptance and who accepted it, in one record

Producing both documents

todaythe certificate of design and the recommendation assembled twice
hereboth derive from one set of evidence, so they cannot disagree
