Description

TAIYO AA-327A GRU-8D OPERATING PROCEDURE

P/N:‌ TAI-AA327A-G8D
‌Applicability:‌ JP-5/Jet A-1 Fuel | Ambient Temp: -40°C to +55°C

‌Pre-Operation Checks‌

‌Ground Safety Verification‌
- Confirm static grounding:
  Resistance ≤10Ω (measured flange-to-truck chassis)
- Install explosion-proof barriers at 5m radius (FM Approved Type)
- Verify intrinsically safe equipment certification (ATEX/IECEx Zone 1)
‌Unit Inspection‌

tabularCopy Code

| Component | Acceptance Criteria | |-------------------|-------------------------------------| | Fuel Hoses | No cracks/swelling (max 3yr service)| | Coupling Valves | DN50 ISO 16028-compliant seals | | Flow Meter | Calibration tag valid (≤6mo old) | | Emergency Stop | Functional test passed |

‌Refueling Sequence‌

‌Step 1: Aircraft Connection‌

plaintextCopy Code

1. Engage grounding interlock:

▷ Attach clamp to aircraft hardpoint (e.g., MLG lug)

▷ Confirm continuity LED (green) illumination

2. Couple dry-break adapter:
• Align ISO 16028 guide pins
• Rotate collar until “CLICK” (15±2 Nm torque)

‌Step 2: Pressure Ramp-Up‌

iniCopy Code

[System Parameters]

Pre-charge = 50 kPa (5 sec hold)

Main pressure = 300 kPa ±10%

Max flow rate = 1,800 L/min

Overpressure cutoff = 350 kPa (0.5s response)

‌Step 3: Monitoring Protocol‌

‌Critical Alarms:‌
tabularCopy Code

| Alarm Code | Condition | Action | |------------|----------------------------|----------------------------| | E01 | Static resistance >25Ω | ABORT - Recheck grounding | | E07 | Fuel temp >49°C | Reduce flow to 800 L/min | | E13 | Particle count > ISO 18 | Stop - Filter bypass risk |

‌Emergency Procedures‌

‌Scenario 1: Fuel Release‌

textCopy Code

1. HIT EMERGENCY STOP (red mushroom button)



2. Activate spill containment:

▷ Deploy absorbent boom (P/N: TAI-SPK01)

▷ Isolate sector within 15m radiu

 3. Purge lines with nitrogen (25 psig max)

‌Scenario 2: Fire Incident‌

textCopy Code

1. Trigger fire suppression system (Halon 1211)

2. Execute shutdown sequence:

• Close master valve (lever position )

• Disconnect aircraft coupling within 20s

‌Post-Operation Actions‌

‌Draining & Purging‌

textCopy Code

a. Engage defueling mode (control panel SW-3 ON) b. Run pump at 10% capacity for 30s c. Inject 15L preservative fluid (MIL-PRF-27601)
‌Preventive Maintenance Log‌
