Urgent SB
Usually safety related
What are the 4 compliance recommendations change categories
- SB must be accomplished
- SB is recommended to be accomplished
- SB introduce improvements
- SB for convenience or option
How can you improve the original design of an aircraft with an SB
Modifications to aircraft engine or accessory
Substitute parts
Engine changes
Software change
Are SBs mandatory
No
So times can be mandated by a relevant AD
Benefits of SB
Lower costs in maintenance and improve performance
What is the main purpose of an SB
Improve original design
Once issued can SBs be cancelled
No it cannot be cancelled
It can only be revised or new SB issued
Following an AD what must the type certificate holder or major design approval holder do
Must propose the corrective action/inspection and submit to the CAA for approval
Following approval must alert all known operators or owners of the product to comply with the AD
What are the steps to an AD
- Identify unsafe conditions
- Identify affected aircraft
- Action required
- Compliance time for required action
- Date of entry
Are ADs issued if a problem on an aircraft won’t affect other aircraft
No
Are ADs issued if a problem on an aircraft won’t affect other aircraft
No
When are ADs issued
When unsafe conditions has been determined by CAA
And the condition is likely to exist in other aircraft
What is the purpose of ADs
To restore an acceptable level of safety
What does ADs mandate
Mandate actions to be performed on aircraft
