Vehicle Type : TRAILERS
Body Style : OTHER
Power Train : NR
Descriptive Information : The units were selected by the production dates from when Pratt Intermodal Chassis
started production and then until production of this model was stopped.
The design of this particular model only created a condition where the potential for a
structural failure exists between the front gooseneck section and the mid-rail under
certain load conditions and when the chassis is in the 20-foot configuration. This can
result in bending or cracking of the mid beam of the chassis when a fully loaded or
overloaded 20-foot container is mounted to the trailer. The issue is not present when
the chassis is used in the 40-foot configuration because the load is spread across the
entire chassis and does not result in the potential bending condition.
There are 320 Units involved of model GN30402-EC-6P

configuration.
FMVSS 1 : NR
FMVSS 2 : NR
Description of the Safety Risk : The defect can result in bending or cracking of the mid beam of the chassis
when a fully loaded or overloaded 20-foot container is mounted to the trailer.
Bending of the chassis makes it difficult to remove the container, and it is a
precursor to future cracking if not remedied. If cracking occurs during
Part 573 Safety Recall Report 23V-767 Page 2
The information contained in this report was submitted pursuant to 49 CFR §573
operation, the retracted landing gears will contact the road and the
gooseneck portion of the trailer will be at a severe upward angle. Continued
travel under this condition could result in complete failure of the trailer, and
if the twist locks connecting the trailer to the container fail or are not engaged
the load could be separated from the tractor and/or the trailer.
Description of the Cause : The result can be in the bending or cracking of the mid beam of the chassis
when a fully loaded or overloaded 20-foot container is mounted to the trailer.
The issue is not present when the chassis is used in the 40-foot configuration
because the load is spread across the entire chassis and does not result in the
potential bending condition.
Identification of Any Warning
that can Occur :
a) – The bending of the frame is visibly evident prior to any other failure
as shown in the attached document
b) – As with the bending of the frame, the crack that can result is also very
evident.

Chronology :
• The trailers in question were manufactured between December 2021, through June 2022.
o Production of this model was halted in June 2022 when a single unit was observed to be bent. The unit
was carrying an overweight 20 ft container at the time.
• Pratt Intermodal Chassis was notified by National Chassis, Inc. in September 2022 that one of their
units also suffered a bent midbeam after being used to transport an overweight 20 ft container. No action was
taken at this time due to the failure occurring while the chassis was being operated outside its approved
Part 573 Safety Recall Report 23V-767 Page 3
The information contained in this report was submitted pursuant to 49 CFR §573
operating limits.
• Pratt Intermodal Chassis was notified by DCLI (Direct Chassis Link Inc) in early October 2023 that
similar units of the same design but produced by prior ownership had similar failures while carrying 20 ft
containers that were within weight limits at the time of failure.
o These two chassis were requested to be shipped to PIC for internal investigation as to cause.
o This investigation led Pratt Intermodal Chassis to reassess the sufficiency of the design of this model to
carry containers at the approved ratings.
• On November 3, 2023, a decision was made to begin the recall process of GN30402-EC-6P chassis
produced by Pratt Intermodal Chassis.
o To date no other reports of bent or cracked trailers manufactured by Pratt Intermodal Chassis have
occurred.
Description of Remedy :
Description of Remedy Program : We have prepared an outline of the procedure to remedy the defect.
Below is an outline of that remedy. There is included in the document a
complete VIN Listing and diagrams. Step 3 below includes welding the
trailer in the 40 ft position and allowing use in that configuration only.
1. All PIC GN304302-EC-6P chassis with the following VIN’s are
required to have an inspection for failure as shown following. See below
steps and diagrams for specifics of the inspection and repair procedure.
2. If cracks exist in the area shown in diagram 2 then the unit may
NOT be used and must NOT remain on the road. Please contact PIC via
email at warranty@prattchassis.com for disposition.
3. If no deformation exists in the area of concern shown in diagrams
1 and 2, you may continue to use the chassis in the 40 ft position only, with
the modifications shown in diagrams 3, 4, and 5.
4. Contact PIC at warranty@prattchassis.com with any questions
about performing this inspection and repair procedure.
How Remedy Component Differs
from Recalled Component :
The notification document outlines the procedure to allow the units that
are found to be bent (but not cracked) to be modified and used as a 40 ft
container trailer only. If cracking of the mid-beam has occurred, the unit is
not to be used.
Identify How/When Recall Condition
was Corrected in Production :
The product was discontinued. The remedy for units in the field is to
adapt the trailer to transport a 40 Ft container only. The loading for a 40
Ft container re-distributes the load to the front and rear of the trailer in
lieu of the center. The center mounts for the 20 ft container are to be
eliminated to no longer allow the transport of a 20 Ft container.
The existing design has not been manufactured since the end of June 2022

Pratt Intermodal Chassis
Model GN30402-EC-6P
Owner/Purchaser Letter
NHTSA Recall ID 23V-767
November 30th, 2023
Dear Owner,
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Pratt Intermodal Chassis (PIC) has decided that a defect which relates to motor vehicle safety exists in certain Pratt Intermodal Chassis (PIC) chassis model GN30402-EC-6P trailers. The potential for a structural failure exists between the front gooseneck section and the mid-rail under certain load conditions. This can result in bending or cracking of the mid beam of the chassis when a fully loaded or overloaded 20-foot container is mounted to the trailer. Bending the chassis makes it difficult to remove the container, and it is a precursor to future cracking if not remedied. If cracking occurs during operation, the retracted landing gears will contact the road and the gooseneck portion of the trailer will be at a severe upward angle. Continued travel under this condition could result in complete failure of the trailer, and if the twist locks connecting the trailer to the container fail or are not fully engaged the load could be separated from the tractor and/or the trailer, resulting in an increased risk of a crash. This notice provides an inspection and repair procedure as outlined below. This inspection and repair procedure is required to be performed on all GN30402-EC-6P trailers built during the months of December 2021 through June 2022., The inspection process is expected to take 20 minutes. The repair procedure is expected to take 1.5 hours. The involved VIN listing also appears below. Reimbursement for the repairs and inspection will be issued upon submission of your receipts and repair records. See page two for more detailed information on the reimbursement process.
