E-22. L/H R/H FIREWALL MODIFICATION KIT (50-19).
Subject: Left and Right Side Firewall Assemblies, Modification of, dated 31 March 2003
Purpose: Provide instructions to modify/reinforce existing firewall installation to prevent wear and fatigue cracking.
Model:
UH-60A
Description: The following is a brief overview of the work required to modify left and right side firewall assemblies. New
doublers, angles, straps, and spacers are installed to left and right firewall assemblies.
Drawings required for modification:

NOTE
• A complete review of this SSI is recommended before modifying right and left side firewall assemblies.
• Before beginning this modification procedure, use the material information list to inventory the kit. Make
sure all parts are present and in serviceable condition.
• Where drawing numbers are not listed within individual steps, drawing(s) listed in preceding step(s) are
the controlling authority.
• The sheet metal and structural modifications in this SSI shall be done by personnel experienced in reading
modification drawings. Routine steps such as cleaning, layout and drilling, deburring, standard repairs,
corrosion control, clean up after rework, chemical coating for aluminum after cutting/trimming parts, paint
touch up, and safety practices may not be called out herein. However, these steps and all other required
routine tasks shall be done.
• Slight variations to the instructions contained herein are allowed, as long as the intent of the modification
is accomplished.

• A complete review of this SSI is recommended before incorporating the engine cowl assembly modification
kit.
• Before beginning this modification procedure, use the material information list to inventory the kit. Make
sure all parts are present and in serviceable condition.
• Slight variations to the instructions contained herein are allowed, as long as the intent of the modification
is accomplished.
• The sheet metal and structural modifications in this SSI shall be done by personnel experienced in sheet
metal/structural work, skilled in reading modification drawings, standard working/repair, and safety
practices. Routine steps such as cleaning, layout and drilling, deburring, standard repairs, corrosion
control, clean up after rework, chemical coating for aluminum after cutting/trimming parts, and paint
touch up may not be called out herein. However, these steps and all other required routine tasks shall be
done.
• Where drawing numbers are not listed within individual steps, drawing(s) listed in preceding step(s) are
the controlling authority.
• When installing fasteners refer to drawing sheet and zones for rivet code on applicable drawings.
A.
Preparation for modification:
(1)
Confirm all warnings, cautions, and notes are complied with per reference (a).
(2)
