Perform 737-800 Startup Assessment using eAuditor
A 737-800 Startup Assessment is a structured evaluation of an aircraft’s systems and procedures during the engine start and pre-flight phase to ensure operational readiness, safety, and compliance with airline and regulatory standards. Performing a 737-800 Startup Assessment using eAuditor allows flight crews and maintenance personnel to digitally standardize assessments, capture real-time evidence, identify discrepancies early, and track corrective actions to ensure safe and efficient aircraft operations.

- Aircraft identification and documentation verification
- Cockpit pre-start configuration
- Electrical and avionics systems check
- Fuel, hydraulic, and pneumatic system verification
- Engine startup and monitoring
- Flight control and safety systems verification
-
Preparing the 737-800 Startup Assessment in eAuditor
2.1 Digital Checklist Configuration
Create a 737-800 Startup Assessment checklist in eAuditor that captures:
- Aircraft registration, fleet number, and flight hours
- Flight crew and maintenance personnel are involved
- Date, time, and location of assessment
- Step-by-step startup procedure checkpoints
Checklist features should include:
- Yes / No / Not Applicable responses
- Mandatory comments for deviations or non-compliance
- Photo and system monitoring screenshots for evidence
- Automated corrective action creation and tracking
2.2 Standards Alignment
Align the assessment with:
- Boeing 737-800 manufacturer startup manuals and checklists
- Airline standard operating procedures (SOPs)
- FAA or EASA operational and safety regulations
-
Aircraft Identification and Documentation Verification
During the 737-800 Startup Assessment, verify:
- Aircraft registration and airworthiness documentation
- Flight logs, maintenance status, and deferred defect list
- Crew authorization and certifications
- Current software and avionics updates
-
Cockpit Pre-Start Configuration
- Verify cockpit master switches and avionics power configuration
- Confirm cockpit warning and annunciator panels are operational
- Check oxygen systems and emergency equipment
- Set flight instruments and navigation systems to pre-start mode
-
Electrical, Avionics, and Instrument Checks
- Test electrical buses, battery status, and external power connections
- Verify avionics initialization and software system readiness
- Confirm radios, autopilot, and flight management systems online
- Check displays, warning lights, and annunciator panel functionality
-
Fuel, Hydraulic, and Pneumatic Systems Verification
- Check fuel quantity, pressure, and distribution
- Inspect hydraulic system pressure and fluid levels
- Verify pneumatic and bleed air system functionality
- Confirm fuel pumps, valves, and crossfeed operation
-
Engine Startup and Monitoring
- Follow the manufacturer’s startup procedures for engines
- Monitor N1, N2, EGT, oil pressure, and temperature parameters
- Check for abnormal indications, vibrations, or alarms
- Confirm thrust reverser and engine control system readiness
-
Flight Controls and Safety Systems Verification
- Test ailerons, rudder, elevators, spoilers, and flaps for correct movement
- Verify trim settings and flight control synchronization
- Check autopilot engagement readiness
- Confirm emergency and safety systems are operational
-
Defect Identification and Corrective Actions
9.1 Defect Classification
During the 737-800 Startup Assessment, findings should be categorized as:
- Critical: startup or flight must be aborted until resolved
- Major: repair required before flight or further operation
- Minor: document and monitor for future maintenance
9.2 Corrective Action Management
Using eAuditor:
- Log deviations or defects with photos and notes
- Assign corrective actions to the responsible personnel
- Track completion, verification, and close-out digitally
-
Reporting and Continuous Improvement
10.1 Assessment Reporting
Generate 737-800 Startup Assessment reports that include:
- Startup procedure compliance status
- Identified defects and risk levels
- Corrective action progress and accountability
10.2 Continuous Improvement
- Analyze recurring startup deviations
- Improve startup SOPs and crew training
- Enhance aircraft reliability, safety, and regulatory compliance
Final Summary
Conducting a 737-800 Startup Assessment using eAuditor ensures the aircraft is operationally ready, safe, and compliant with all manufacturer and regulatory requirements. Digital inspections, evidence capture, and tracked corrective actions provide a standardized, auditable approach to early detection of system issues and operational deviations.
