Installation Bolt Torque
•
Use fully threaded, 3/8-16 bolts meeting requirements of FAA EB83A. (P/N 21716 is
recommended.)
•
Use Heico-Lock or Nord-Lock stainless steel lock-washers per FAA specifications*.
•
Mounting base holes must be degreased, cleaned, and dried prior to bolt installation.
•
Base-to-fixture mating surfaces must be degreased, cleaned, and dried prior to
installation.
•
Apply marine grade anti-seize (K=.18) per manufacturer's instructions to each bolt.
•
Install the 3/8-16 bolts with lock-washers per lock-washer manufacturer's guidelines.
•
See Section 9.2 for Heico-Lock installation guidelines (2014)
•
Achieve a full final torque of 28 FT-LBS (37.9 N-m) ±10% with a calibrated torque
wrench.
•
Impact wrenches are not recommended as installation tools.
•
Check torque and re-torque all bolts within 2 weeks of initial installation.
•
Maintain all bolts by checking and re-torqueing per FAA specifications*.
•
If any lubricants or thread locking compounds are used (not recommended), torque must
be recalculated based on K factor provided by lubricant or compound manufacturer.
•
New bolts and lock-washers shall be used each time a light unit is removed from its base.
*Refer to the following specifications for FAA installation and maintenance recommendations:
•
AC150/5340-26 "Maintenance of Airport Visual Aids"
•
AC150/5345-46 "Specification for Runway and Taxiway Light Fixtures"
•
FAA Engineering Brief No. 83A "In-pavement Light Fixture Bolts"
8" Pro APF IRGL optical assemblies are designed to withstand a maximum torque
WARNING
superior-grade 3/8" hardware, however other components within the light fixture
installation (i.e. base-can, extension rings, spacer rings, etc.) may not be capable of
supporting such a load. Eaton Crouse-Hinds recommends following the installation
