1. Support Equipment (SE). SE includes equipment such as tow tractors, air conditioning units, tow bars, electrical power units, test sets, cables, jacks, etc. used in support of aircraft maintenance. The qualification/certification and licensing of SE operators is covered under the Quality Assurance/Analysis section of this guide. SE safety is covered under the Safety section of this guide.

a. Support Equipment Allowances. References:

NAVAIRINST 13650.1	Aircraft Maintenance Material Readiness List (AMMRL)
COMNAVAIRFORINST 13650.3	Aircraft Maintenance Material Readiness List (AMMRL)

(1) Allowances for SE are promulgated in lists tailored to meet individual activity needs. The IMRL establishes the allowances of SE required to perform the assigned maintenance functions. Some items are placed in the reporting custody of an "I" level maintenance activity for use by the squadrons. These custody codes are:

(a) "E" - Assigned to items infrequently used or used less than once a month. Supporting IMA’s are authorized a predetermined quantity consistent with the infrequent use. but only for a short time.

(b) "P" - Assigned to items weighing over 200 pounds, or over 300 pounds for wheeled equipment, equipment exceeding any one of the following dimensions: length six feet, width six feet or height 3 feet. Also assigned to equipment that is fragile or subject to misalignment or loss of calibration through transport. Code “P” is also assigned to equipment that is not coded for infrequent use.

(c) "L" - Assigned to all equipment requiring calibration. These are retained by organizational activities when deployed and are not already coded “E” or “P”.

(d) “M” – This code is used for non-calibrateable assets which are used in conjunction with calibrateable assets.

(2) Consideration must be given to availability of custody coded items when planning for deployment or detachment operations.

(3) Support Equipment Controlling Authority (SECA). A term applied to major aviation commands that exercise administrative control of AMMRL Program SE for allowance and inventory control. The following is a list of designated SECA’s:

COMNAVAIRLANT	SECA L
COMNAVAIRLANT	SECA L
COMNAVAIRPAC	SECA P
CNATRA	SECA T
COMNAVAIRRES	SECA R
COMNAVAIRSYSCOM	SECA S
NAMTRAGRU	SECA E
NAVAIRSYSCOM DET ACC	SECA N

(4) Support Equipment Resources Management Information System (SERMIS). SERMIS is the repository of master data for printing IMRL’s and provides in-use visibility to SECA’s, Naval Inventory Control Point (NAVICP) Philadelphia, NAVICP Mechanicsburg, COMNAVAIRSYSCOM, NAVAIRWARCENACDIV Lakehurst and other select field activities involved in SE management/acquisition.
