Blinking airbag light...
Turned out to the airbag clock spring.
Just before this happens, you could hear a metallic rubbing sound inside the steering wheel.
From what I have been told, a clock spring failure is common for F-150s of that model year.
Here's the trouble code chart
CODE COMPONENT/FAULT
12 Low Battery voltage
13 Air Bag Circuit Shorted to Ground
14 Front Air Bag Sensor and Bracket Circuit Shorted to Ground
21 Rear Air Bag Sensor and Bracket Not Mounted to Vehicle Properly
22 Rear Air Bag Sensor and Bracket Output Circuit Shorted to Battery Voltage
23 Rear Air Bag Sensor and Bracket Circuit Input Feed/Return Circuit Open
24 Rear Air Bag Sensor and Bracket Output Feed/Return Circuit Open
32 Driver Side Air Bag Circuit High Resistance or Open
34 Driver Side Air Bag Circuit Low Resistance or Shorted
41 RH Front Air Bag Sensor and Bracket Feed/Return Circuit Open
42 LH Front Air Bag Sensor and Bracket Feed/Return Circuit Open
44 RH Front Air Bag Sensor and Bracket Not Mounted to Vehicle Properly
45 LH Front Air Bag Sensor and Bracket Not Mounted to Vehicle Properly
51 Air Bag Diagnostic Monitor Internal Thermal Fuse - Fuse Blown Due to Intermittent Short to Ground
52 Backup Power Supply - Voltage Boost Fault
53 Front Air Bag Sensor and Bracket Circuits Resistance to Ground or Air Bag Diagnostic Monitor Fault
- Rapid Continuous Flashing of Air Bag Indicator (No Fault Code) All Primary Air Bag Sensors Disconnected
- No Air Bag Indicator - Inoperative Indicator Circuit or No Battery Positive Voltage to Air Bag Diagnostic Monitor
- Continuous Air Bag Indicator - Air Bag Diagnostic Monitor Disconnected or Inoperative
Hope this helps....

Air Bag Sliding Contact
1. WARNING: THE BACKUP POWER SUPPLY ENERGY MUST BE DEPLETED BEFORE ANY AIR BAG COMPONENT SERVICE IS PERFORMED. TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY POSITIVE CABLE AND WAIT ONE MINUTE.
Disconnect the battery positive cable and wait one minute for the backup power supply energy to be depleted.
2. Make sure the vehicle's front wheels are in the straight-ahead position.
3. Remove the driver side air bag module (043B13)
4. Remove the steering wheel (3600).
5. CAUTION: Do not apply excessive force to the air bag sliding contact (14A664).
Turn the air bag sliding contact clockwise until it stops.
6. Rotate the air bag sliding contact counterclockwise 2.75 turns.
7. Align the marks on the air bag sliding contact with the marks on the outer housing.
8. Install the steering wheel.
9. Install the air bag module as described in Module, Driver Side Air Bag, Removal and Installation in this section.
10. NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.
Connect the battery positive cable.
11. Verify that the air bag indicator is operative.
