CJ series on unsealed strips

[Bang Bus]

Looking through the limitations section of the AFM for the CJ3 is states that operations are only allowed on paved runways, no mention of the same limitation that I could find in the CJ 1 or 2 manaul. Does anyone have any experience with CJ's on unpaved strips?? gravel kits???

CJ can be fitted with a gravel kit, CJ2 not - as there wasn't much uptake with the CJ.
Have flown a CJ with the G-kit and didn't think it really did much.

Yes I have also seen, that there is no limitation concerning type of a RWY, in AFM of CJ2. Very strange.

Perhaps this implies operations on unsealed strips are permitted???

Bang Bus,
Don't forget that the CJ3 is certificated under FAR 23 as commuter category unlike the smaller CJ's and thus has to comply with different regulations.

Chinchilla.612. you're not quite right there.

Just for your info, all of the light jets below 5,700kgs are certified under FAR/JAR23 (The CJ series has continued to do so as they have upgraded the models)

However all performance is certified to FAR/JAR25 Commercial standards.

If you look at all of the performance figures for all CJ models EXCEPT the classic CJ (which has a gravel supplement) it within the simplified section it specifies PAVED RUNWAY to use simplified figures. Under FAR/JAR25 the aircraft is to use paved surfaces unless a supplement is published. The rest of the CJ series has no supplement, therefore grass/gravel is not an option.

Citations have a habit of nose-ing in on grass, if they don't have a nosewheel spin-up modification required for operations off paved surfaces.

Hope this is of a little help.

Steak&Kidney_Pie,

I guess that depends on how you read what I wrote lol.
Yes FAR 23 is common, but because of the CJ3 (C25B) being over the 12,500lb mark it was certified under the Commuter category, which the lighter C525 models were not.
This had implications such as the additional requirements for a smoke detection system in the baggage holds, an annunciation to display if the emergency exit is insecure and a prohibition on takeoff with defective anti-skid function (among other requirements of course).
Whether this affected landing on paved runways or not I am not sure, and only suggested that the different regulations affecting the CJ3 compared to the smaller varients MAY have been a factor.
