What is an aircraft product?
An aircraft product is an aircraft engine or propeller.
What is required before an aircraft is awarded a type certificate?
The engines and propellers must first also gain Type Certification.
Who is responsible for the issue of the Type Certificate and who is the holder?
The type certificate is issued by the NAA (CAA) and the holder is the manufacturer.
The type certificate holder is the only agency which can apply to change the type design (limited changes may be made by the application for a supplementary type certificate).
What is issued along with the award of a Type Certificate?
Along with the Type Certificate, a Type Certificate Data Sheet is issued, which details the:
Type and Mark, Dimension and Weight, Type of Engines, Equipment fitted, Etc.
What is the purpose of a Supplementary Type Certificate and who is responsible for its issue?
The Supplementary Type Certificate is issued by the NAA. It’s is issued to indicate that a modification to an aircraft or aircraft product is approved.
A supplementary type certificate is issued to an organisation that is not the type certificate holder.
What is a Certificate of Airworthiness issued to?
A Certificate of Airworthiness is issued for one aircraft only and the serial number is shown on the certificate.
This is held by the aircraft operator.
Who holds the Certificate of Airworthiness?
The Certificate of Airworthiness is held by the aircraft operator and a copy is carried on the aircraft at all times.
Does the Certificate of Airworthiness mean the aircraft is automatically fit to fly?
No. The C of A is only valid if the aircraft is maintained in accordance with the maintenance schedule.
When is an aircraft considered orphaned?
If the legal person holding the TC ceases to exist (results in TC holder not complying with responsibilities).
If the TC holder no longer complies with their regulatory obligations. A typical case is when the TC holder loses the Design Organisation Approval (DOA)
The TC holder surrenders the TC.
How can an orphaned aircraft continue to be operated?
An orphaned aircraft can only continue to be operated if they hold a
Restricted Certificate of Airworthiness
Or
A Permit to Fly
When is a Permit to Fly to issued?
Generally, a Permit to Fly is issued when a C of A is temporarily invalid.
For example,
As a result of damage
Or
When a C of A cannot be issued because the aircraft does not comply with the essential requirements for airworthiness.
IE.
The aircraft does not conform to an approved design.
An airworthiness limitation, a certification maintenance requirements or an airworthiness directive has not been complied with.
The intended flights are outside of the approved envelope.
What is a Certificate of Registration and who is responsible for its issue?
A Certificate of Registration is issued before an aircraft enters service and is issued by the NAA of the country of registration.
An aircraft can only hold one Certificate of Registration, if it is sold abroad the Certificate of Registration must be returned to the NAA and a new one applied for in the country of purchase.
Who is responsible for setting the levels required for a Noise Certificate?
Noise Levels are set by international agreement and are usually the same in each individual country.
In accordance with the weight schedule, when should the aircraft be weighed after manufacture?
An aircraft should be weighed two years after manufacture and every five years after that.
In addition to scheduled weighing, when should the aircraft be weighed?
The aircraft should be weighed whenever after any process which has the potential to change the weight of the aircraft.
IE.
After Painting
Or
After Major Structural Modification,
Etc.
Who is responsible for holding the weight schedule and weight and balance data?
The weight and balance data is held by the operator.
What act covers the issue of a radio licence and who is responsible for its issue?
The radio licence is covered by the wireless telegraphy act and is issued by the office of communications (OFCOM) in the UK.
What type of modification is a change of radio equipment considered as?
A major modification and requires an air test along with further procedures.
Considering Aircraft Technical Manuals,
Who is responsible for revision and who is a recipient of the revision of manuals?
The revisions and list of revisions must be provided by the manufacturer or design authority.
It is provided to all operators of that aircraft.
When a discrepancy is shown between the revision status of two documents, which should be used?
The latest revision must be used when a discrepancy is shown between revision statuses of multiple documents.
What does ATA stand for and when was it formed?
