INTRODUCTION
This publication contains shop maintenance instructions with Illustrated Parts List (IPL) for the Aircraft
Navigational Light Anti-collision, Flashtube, part number 30-1033-ALL, manufactured by Grimes Aerospace
Company and hereafter referred to as the navigational light.
The instructions in this publication provide information necessary to do maintenance functions ranging from
simple checks and replacement to complete shop-type repair.
The instructions only apply to the navigational light part number listed above. Be sure the part number on the
navigational light is listed on the title page before performing any of these instructions.
This publication is written to the Air Transportation Association of America (ATA) Specification Number 100
and will be revised as necessary to show current information.
This publication is divided into sections as shown in the preceding Table of Contents. Also refer to the Table
of Contents for page location of each applicable section.
An explanation of how to use the Illustrated Parts List (IPL) is provided in the introduction of that section.
The following sections of this publication have been verified on the date(s) specified. Where actual
performance of the functions (tasks) cannot be performed prior to issuing a manual, those functions (tasks)
shall be verified by simulation. Any function (task) verified by simulation must be verified by actual
performance at the earliest possible time.
A. The navigational light is installed on aircraft to provide a flashing source of high-intensity illumination
to indicate aircraft position.
B. The navigational light uses a flashtube lamp assembly to provide illumination. The flashtube lamp
assembly fires at a rate of 40 to 60 flashes per minute and uses a parabolic reflector to control the
emitted light pattern. The flashtube lamp assembly is protected by a heat-resistant glass lens. The
glass lens provides the specified aviation color as per MIL-C-25050.
C. The navigational light has a Printed Circuit Board (PCB) assembly that provides voltage limiting,
timing and anti-afterglow circuitry.
2. Operation.
A. The navigational light requires a 28 Vdc input (Figure 2) from the aircraft electrical system. The
voltage is applied to the power conversion circuit. The output of the power conversion circuit is
applied to both the storage capacitors and control circuit. The control circuit is made up of voltage
limiting, timing and anti-afterglow circuits. The timing circuit provides a trigger to the flashtube, which
fires and provides a flashing source of illumination.
B. The 28 Vdc input is applied to the primary winding of transformer T1 (Figure 3) through choke L1.
Zener diode VR1 and capacitor C2 provide a 10 Vdc reference voltage to the timing and anti-
afterglow circuits.
C. The induced voltage on the secondary winding of T1 is applied to storage capacitors C9, C10, C11
and C12. These capacitors charge to 430-570 Vdc and discharge through the flashtube lamp DS1
to produce a 27 Joule, minimum, flash.

PART NUMBER 30-1033
D. A positive pulse is developed at operational amplifier U2 pin 2. The pulse is applied to the gate of a
Silicon Controlled Rectifier (SCR). SCR1 fires, discharging capacitor C7 through transformer T2,
which results in the storage caps discharging through DS1. Potentiometer R26 controls the timing of
the firing rate of flashtube lamp DS1. Potentiometer R26 and resistor R11 provide voltage limiting
for the PCB assembly.

1. General Information.
A. The Illustrated Parts List (IPL) provides a breakdown of assemblies, subassemblies and detail parts
of the aircraft navigational light. All parts are listed, except for parts which lose their identities by
being permanently fastened to other parts or are part of an assembly not subject to disassembly.
B. Bulk materials such as safety or electrical wire and tape, and consumable materials such as
adhesives, sealants, lubricants, solder, paint and primer are not included in the detailed parts lists.
These materials are identified in the materials list at the beginning of each section.
C. To find a part number when the part number is unknown, locate the part on the illustration and note
the item number. Locate the item number on the detailed parts list. The part number will be shown
on the same line. In some instances there are gaps in item number sequence and the item numbers
are not continuously sequential.
2. Explanation of Columns, Terms and Symbols in the Illustrated Parts List (IPL).
A. FIG. & ITEM NO. column: The figure and item numbers key the detailed parts list to the applicable
illustration. The first number represents the figure number of the illustration. The item number
corresponds to an item number on the illustration.
(1) An item number not on the illustration is identified by a dash (-) preceding the item number.
This can indicate the following:
(a) When two or more visually alike parts are listed in sequence, only the first part is
illustrated. The illustration, however, is applicable to both parts.
(b) When detail parts of an assembly or installation are separately illustrated, the resulting
assembly may be illustrated as an assembly by bracketing the detail parts and identifying
the bracket as the assembly. If brackets are not used, the detail parts are illustrated, but
the assembly is not.
(2) An item number followed by an alphabetical character such as A, B, C, etc., indicates the part
listed is similar to the same item number without the alphabetical character. The difference
could be each part is used for a different next higher assembly (NHA) or is an equivalent part.
This will be noted in the NOMENCLATURE or EFF CODE columns.
B. PART NUMBER column: This column contains the original manufacturer’s part number of the
assembly, subassembly or detail part listed. Part numbers in this IPL are those of Grimes
Aerospace Company, Urbana, Ohio (V72914) or are standard parts unless a Commercial and
Government Entity (CAGE) code appears in the NOMENCLATURE column. Refer to paragraph 4
for details. The following phrases may be used in this column:
“ORDER NHA” is used when no part number exists for the part listed or when it is preferable to
order an assembly rather than detail parts. ORDER NHA items which have no part numbers
are not procurable and should not be ordered. The next higher assembly, however, is
procurable and may be ordered.
“REF” followed by an assigned number (for example REF001) is used when the part number is
more than fifteen digits. The original part number with more than fifteen digits is listed in the
NOMENCLATURE column and is the part number to be used when ordering the part.
C. AIRLINE STOCK NO. column: This column is reserved for airline part numbers and accommodates
eleven numbers.
D. NOMENCLATURE column: This column identifies the parts being listed by noun name followed by
modifiers when applicable. This column also provides the following information:
(1) The relationship of each listed item to its next higher assembly (NHA) is shown by an indenture
code. Each listed item is placed in the NOMENCLATURE column one indenture (one dot) to
the right of the assembly to which it belongs. Items at equal indentures are all components of a
single assembly or subassembly. An example of the indenture code system is shown below:
12 3 4 5 6 7
(2) Symbols used, with the exception of effectivity and CAGE codes, are as follows:
“REPLACES” or “REPLACES ITEM XXX” identifies this part is newer and therefore more
desirable than the “REPLACED” part. However, either may be used.
“REPLACED” or “REPL BY ITEM XXX” identifies this part is older and therefore less
desirable than the “REPLACES” part. However, either may be used.
“ALTN PART FOR ITEM XXX” identifies this part as an alternative. However, either part
may be used and neither is more desirable than the other.
“TPN” precedes a True Part Number with all dashes, slashes, spaces and/or symbols
assigned by the original manufacturer of the part. This is the part number to be used
when ordering the part.
E. EFF CODE column: This column establishes part relationship with assemblies, which are essentially
the same, but have minor variations. These assemblies are the end items on the detailed parts list
and are assigned reference letters such as A, B, C, D, etc. Subassemblies or detail parts, which are
not common to all configurations, but are associated with one or more of the coded end items, carry
the letter or letters assigned to the end item(s) with which they are associated. If a part is common
to all end items, the EFF CODE column is blank.
F. UNITS PER ASSY column: This column shows the quantity of each item required for the next higher
subassembly, assembly or installation outline. Quantities shown for attaching parts are the number
required for the related part, subassembly or assembly and, therefore, may not be the total quantity
used for the end item of the detailed parts list. The following letters may be used in this column:
“AR” indicates “as required” and refers to variable quantity items such as shims, spacers or
similar items.
“RF” indicates "reference" and refers to items and their quantities which are listed elsewhere
and are provided here as a reference only.
"NP" indicates "non-procurable" and refers to items which are not procurable and may not be
ordered.
3. Abbreviations. Standard abbreviations used in the IPL agree with MIL-STD-12, except as noted below:
Abbreviation Definition
None
A. CAGE codes, preceded by the capital letter "V" (V12345), are used to identify the original
manufacturer of non-Grimes Aerospace Company (V72914) components. CAGE codes are listed in
the NOMENCLATURE column, except for the government codes below, which are not listed:
