Discussion / Agenda
1. Bombardier Flight Operations
2. Scheduled Maintenance
3. Lease Return / Transfer of Ownership
4. Functional Check Flights Guidance
3
1 Bombardier Flight Operations
Supports the following:
Production flights tests to validate the compliance of a new production aircraft to the type certificate
Experimental verses production flight tests Specific training is required for both roles
Customer Acceptance Flights
Lease Return / Transfer of Ownership
“Specific” Functional Check Flights
CS300 aircraft
4
2 Scheduled Maintenance
Functional Check Flights should only be conducted as per the approved AMM Task
Dash-8: Only requirement is a trim check after an aileron replacement
CRJ: Only requirement is an optional ADG flight check (Task could be conducted on ground with a back drive unit)
If Operator requires a Functional Check Flight post Maintenance,Bombardier Recommends a Normal Flight Profile
5
2 Scheduled Maintenance
Normal Flight Profile
A flight similar in nature to the customers operational flight profile
Consider Date sensitive parts Consider Cycle sensitive parts
CRJ1000 NextGen aircraft
6
3 Lease Return / Transfer of Ownership
Guidance on procedures acceptable for aircraft transfer / return.
Review the contract / lease.
Meet with the owner or their representative to discuss their requirements
Agree prior to the flight, what are the conditions of an acceptable flight
Ensure flight is flown in accordance with the AFM

Functional Check Flight - Preparation
The Aircraft
Why is a Functional Check Flight Required?
What was the condition of the aircraft prior to maintenance?
What areas of the aircraft were maintenance tasks carried out?
Did maintenance have any issues carrying out the maintenance tasks?
What is the current condition of the Aircraft?
What Aircraft Documents are valid for the Flight?
Conduct a Detailed Briefing with the Maintenance Team
9
Functional Check Flight - Preparation
The Flight Profile
Do you need ground runs?
CS100 aircraft
10
Ground Runs
Check for any Airport Restrictions
11
Functional Check Flight - Preparation
The Flight Profile
Do you need ground runs?
Consider a “High Speed Taxi”
What is the Airport Crash Fire Response Level? (Departure and Alternate Airport)
Do you have two way comms with Maintenance during the flight?
Talk to The Airport Authorities
12
Functional Check Flight - Preparation
The Flight Profile
What airspace do you require?
CRJ700 NextGen aircraft
13
Airspace
Talk to Air Traffic Control - Time the Flight With Available Areas
14
Airspace
Discuss Lost Comm Procedures
15
Functional Check Flight - Preparation
The Flight Profile
What environmental conditions do you require?
CRJ900 NextGen aircraft
16
Functional Check Flight - Preparation
Environmental Factors to Consider:
VMC IMC Precipitation Runway Condition Turbulence Day Night
17
Functional Check Flight - Preparation
Airport Considerations:
Minimum Weather for Take-off Minimum Weather for Alternate Airport
Bombardier uses a sliding scale for 1st Flights:
CYMX Weather Minimums CYUL/CYZD Weather Minimums
Ceiling (Feet) Vis SM Ceiling (Feet) Vis SM
3500 3 3500 3
3000 4 3000 4
2500 5 2500 5
2000 6 No icing conditions
No icing conditions
18
Functional Check Flight - Preparation
The Flight Crew Based on Aircraft
condition/requirements, ATC limitations – Create a Functional Check Flight Profile and Check Flight Card.
Determine who needs to be on board? Review Crew Qualifications / Recency Systems Review of all system to be
checked Review Emergency Procedures related
to Maintenance Completed Review crew actions in the event of a
system failure – Establish flight abort criteriaCrew Must Understand the Operation of the Systems
Recommend a Crew with Strong Technical Background
19
Component Level Pre-Flight walk around A FCF walk around is not a normal walk around.
Crew Must be looking for the proper indications when selecting systems on/off, changing flight modes, or configuring the aircraft
Flight should be flown as per the plan Points of interest should be noted by:
FDR Event Marker - Pressed Log: Time of Event, Aircraft Altitude, Airspeed, & Configuration If crew was conducting a maneuver or configuration change, document
crew actions at the time of event
If at anytime a system failure occurs, the continuation of the flight should be assessed as per the defined Pre-Flight Abort Criteria
Functional Check Flight – Conduct of Flight
Accept No Unnecessary Risk
20
Provide a detailed debrief to Maintenance
Download the FDR for Review
Flight is not finished until the paperwork complete
Functional Check Flight – Post Flight
Ensure Maintenance Team Clearly Understands Any New Flight Discrepancies
21
Summary
Functional Check Flights must never intentionally go outside AFM limitations
Functional Check Flights should only be flown if required by the AMM and as per the AMM
If a Functional Check Flight is Required, Fly a Normal Profile
Prepare a detailed plan for the Functional Check Flight
“Fly the Plan”
If in doubt, land!
