Comprehensive practice flashcards covering all 5 sources of P-8A lecture notes, including fueling limits, move procedures, emergency actions, corrosion MAFs, dimensions, and panel specifics.

How long do fuel samples last for, and what must be completed prior to taking samples or handling hazmat?

Fuel samples last for $24\text{ hours}$. Prior to taking samples or handling any hazmat, you must read the Safety Data Sheet (SDS), which can be found in the Tool Room.

How long should you wait to take fuel samples after an aircraft has moved or fueled, and why?

You must wait $2\text{ hours}$ to allow contaminants to settle to the bottom so an accurate sample can be taken. Water settles at a rate of approximately $1\text{ foot per hour}$ within the fuel tanks.

What contaminants may be present in fuel samples?

The contaminants include discoloration, microbial growth, water, dye, particulate matter (dirt and debris), and emulsions.

What procedure should be followed if a fuel sample contains contaminants?

If contaminants are present, retain the sample, drain $5\text{ gallons}$ of fuel into a suitable container, and take a second sample. If contaminants are in the second sample, retain it and immediately notify maintenance control, then bring both retained samples to QA for inspection. If the first sample contains microbiological contaminants or dye, retain it, immediately notify maintenance control, and bring it to QA.

Who is authorized to inspect fuel samples?

A Naval aircrewman designated by the Commanding Officer (CO) per NATOPS Evaluation Report (OPNAV 3710/7), the Line/Power Line Supervisor, a CDI, a CDQAR, or a QAR.

Is APU or external power required to take fuel samples on the P-8A, and why?

Yes, APU or external power is required because hydraulic power is needed to open the weapons bay.

What materials are required to clean a fuel sample kit?

Alconox, lint-free cloths, and water.

How many fuel boost pumps are on the P-8A and where are they located?

There are $6\text{ AC boost pumps}$ and $1\text{ DC boost pump}$. There are two for each main tank, two for the center tank, and the DC pump is connected to main 1.

What step-by-step procedure is used to transfer fuel using the boost pumps?

1. Move the defueling valve to the open position. 2. Turn on the boost pumps in the tank you want to remove fuel from. 3. Open the cross feed valve. 4. Move the refueling valve switch to the open position for the tank you want to move fuel into. 5. After fuel transfer, turn the boost pumps off. 6. Close the cross feed valve. 7. Return the defueling valve to the closed position.

What is the 3% limit during fueling?

It is the air-to-fuel ratio reserved to allow fuel expansion based on temperature differences.

What are the limitations of fueling the P-8A on battery power only?

The aircraft must be put in ground fueling mode within $5\text{ minutes}$ of turning on the system (otherwise SPDS automatically shuts it off). A fully charged battery allows fueling for up to $15\text{ minutes}$ while leaving enough charge to start the APU. Only main tanks 1 and 2 and the center tank can be filled.

What is the ratio forward to aft when fueling the P-8A, and how do you fuel an AAS configured aircraft?

The standard ratio is $1/3\text{ forward to } 2/3\text{ aft}$. For an AAS configured aircraft: fuel mains 1 and 2 and the center tank to capacity, fill the aft tanks to capacity, and finally fill the forward tanks as instructed by maintenance control.

How many fuel tanks and tank groups are on the P-8A, and how are the groups divided?

There are $10\text{ fuel tanks}$ divided into $6\text{ tank groups}$: Main 1, Main 2, Center (3), Forward (4, 5, 6), Mid (7, 8, 9), and Aft Integral (10).

What is the proper pressure for refueling operations?

$33\text{--}55\text{ psi}$.

What is the purpose of the surge tanks and what happens if fuel level in them is too high?

Surge tanks collect fuel overflow from main tanks 1 and 2. If the fuel level is too high, fuel will drain out of the vent scoop.

What is the difference between a CP MAF and a CT MAF, and what is the drop dead date for both?

CP MAF (Corrosion Prevention): Used when bare metal is exposed but no corrosion has formed; identified by a shiny metallic surface. CT MAF (Corrosion Treatment): Used when any corrosion has formed; identified by dull, white, or reddish colors. The drop dead date for both is $28\text{ days}$ out, including the day written.

What is the procedure if you are directing an aircraft and the pilot is not following your hand signals?

Signal the pilot to stop and notify maintenance control to make contact with the aircraft to establish communications.

What is the procedure for an engine fire during engine startup?

Signal the pilot to shut down the affected engine and notify the pilot of a fire using proper hand signals. Then notify maintenance control to contact emergency services.

What hand signal rules apply when communicating with pilots versus ground crew according to 00-80T-113?

Pilot hand signals are given above the shoulders/head. Ground crew hand signals are given at or below the waist.

Why is it necessary to lock out the nose wheel steering with the steering lockout pin?

Installing the lockout pin isolates nose wheel hydraulics, preventing damage to the nose landing gear, towing equipment, and ground personnel by removing nose landing gear movement under its own power.

What is the maximum turning radius of the P-8A, and what is required to turn up to or past 90 degrees?

Maximum normal turning radius is $78^\circ$. Disconnecting the torsion link is required to turn up to $90^\circ$. Disconnecting the nose taxi light wire is required to turn past $90^\circ$. Turning radius limits are indicated by red lines on the nose landing gear door.

How fast can an aircraft be towed, and why must it be towed 10 feet in a straight line after turning?

The aircraft can be towed up to $5\text{ mph}$ (or as fast as the slowest wing/tail walker). Towing $10\text{ feet}$ in a straight line after turning aligns and relieves tension on the torsion links.

What happens in the event of a tow bar separation during an aircraft move?

The move director gives two short horn blasts (if one horn blows, all horns blow). If Pushing: Move director blows horn twice, driver stops completely, brake rider applies brakes on director's signal. If Pulling: Move director blows horn twice, driver pulls backwards at a $45^\circ$ angle until clear, brake rider applies brakes on director's signal. Wing/Chock walkers cautiously attempt to place chocks in the wheel path.

Why should brakes not be applied during aircraft movement in cold weather?

Application of the brakes in cold weather may cause O-rings to shrink and leak brake fluid.

What is the procedure for an APU fire aboard the aircraft?

Enter the flight station, pull the APU fire handle upward and twist in either direction until it stops (or hold until 'FIRE BOTTLE DISCHARGED' light illuminates). Move the APU master switch to OFF, then move the battery switch to OFF. Ensure all personnel evacuate the aircraft and notify maintenance control to call emergency services.

Where are the deployment mechanisms for the APU fire bottle located?

1. Center Console in the flight station. 2. Starboard aft bulkhead of the main landing gear wheel well.

What is the procedure for an APU fire during refueling operations?

Stop fuel flow, disconnect the fuel line, deploy the APU fire bottle from the main wheel well, evacuate all personnel aboard the aircraft, and notify maintenance control to call for emergency services.

Where are emergency response kits located (AED, fuel spill, battery spill, tire deflator)?

AED: Maintenance Control and Duty Office. Fuel spill kit: Hangar between supply and line shack. Battery spill kit: Hangar in front of the AE shop. Emergency tire deflator kit: Frame/Mech shop.

How many personnel are required to move an aircraft according to publication NA 00-80T-96 versus VP-4 SOP?

NA 00-80T-96 requires a minimum of $6$ qualified individuals. VP-4 SOP requires $9$ individuals with brakes or $11$ individuals without brakes (chock walkers are required when moving without brakes).

What are the 8 named positions required for an aircraft move?

Director, Senior Observer, QA Representative, Driver, Brake Rider, Wing Walker (x 2), and Tail Walker (x 2).
